The advent of digital computers and the availability of ever cheaper and faster micro processors have brought a tremendous amount of control system applications to the automotive industry in the last two decades. From engine and transmission systems, to virtually all chassis subsystems (brakes, suspensions, and steering), some level of computer control is present. Control systems theory is also being applied to comfort systems such as climate control and safety systems such as cruise control or collision mitigation systems.

A Hardware-in-the-Loop (HiL) system for Electronic Control Units (ECU) of electro-pneumatic brake systems is presented. The HiL system runs a real-time capable vehicle model comprising of both the vehicle dynamics and the electro-pneumatic brake system. The dynamic behaviour of the vehicle can be simulated either by a real-time multi-body vehicle model or by a simpler system dynamic (double-track) model. To assess the quality of the system dynamic vehicle model, it was compared to the multi-body vehicle model which was validated with comprehensive experimental results. Discrepancies can be seen for highly unsteady manoeuvres. Reasons for these discrepancies caused by the modelling topology of the system dynamic vehicle model will be given. In order to simulate the electro-pneumatic brake system, a real-time model has been developed and validated. The different topologies of brake systems can be assembled from components and integrated into the vehicle model.

The use of design of experiment (DoE) and data-driven simulation has become state-of-the-art in engine development and calibration to cope with the drastically increased complexity of today’s engine ECUs (electronic control units). Based on the representation of the engine behavior with a virtual plant model, offline optimizers can be used to find optimal settings for calibrating the engine controller’s calibration, e.g. with respect to fuel consumption and exhaust gas emissions. This increases the efficiency of the calibration process and reduces the need for expensive test stand runs. The present paper describes the application of Gaussian process regression, a statistical modeling approach that outperforms previous solutions based on polynomial models and artificial neural networks in terms of achievable model accuracy and usability. The implementation of the algorithms in a commercial tool framework allows for a broad use in series engine calibration.

ADAS applications are becoming increasingly important for today's commercial vehicles. It is therefore crucial that different ADAS functionalities interact seamlessly with existing ECU networks. For example, autonomous emergency braking (AEB) assistants directly influence the brake ECU and engine control. It has already become impossible to validate this growing interconnectedness of control interventions in vehicle behavior reliably with prototype vehicles alone. The relevant tests must be brought into the lab at an earlier development stage, to evaluate ECU interaction automatically. This paper presents an approach for using hardware-in-the-loop (HIL) simulation to validate ECU networks for extrememly diverse ADAS scenarios, while taking into account real sensor data. In a laboratory environment, the sensor systems based on radars, cameras and maps are simulated realistically with a combination of simulation and animation.

CONVENIENT is a project where prediction and integrated control are applied on several subsystems with electrified actuators. A primary project goal is to develop a model-based optimal controller that uses predictive information in order to minimize fuel consumption. Another goal is to develop a control structure that both supports optimality and modularity since there is a need of adapting the controller to various truck configurations. A high-level controller denoted “Predictive Energy Buffer Control” controls several energy buffers in an integrated and optimal way using model predictive control. Several buffers are considered, such as the cooling system, the battery, and the vehicle kinetic energy. Controlling the vehicle kinetic energy means that when in cruise control mode the vehicle speed is varied with respect to the set speed in a fuel efficient way. Another focus is the communication between the driver and the control system.

Electric parking Brake was introduced in 2000 with an actuator integrated into the caliper, controlled by a standalone ECU. Then a variety of actuator technologies were realized. Cable pullers, motor on caliper, actuator in drum in hat with different control concepts. In 2012 the boom started - with a concentration on caliper integrated systems and with an integration of the ECU into the ESC system. New developments are requiring EPB out of different aspects - comfort and controllable standstill are requested. So EPB systems have to be adapted to the upcoming situation. Under the influence of the commercial situation the EPB systems and actuators have to be updated with a focus on standardization, modular boxes and simplification. A look on system and actutor principles and solutions shows a way to fullfill these requirements.

Bus bars are very critical components for power distribution in Electric Drive systems. The increase of power electronic components on vehicles, and their interaction, has increased the possibility of noticeable and destructive amplitude harmonics at resonant frequencies to exist in the power distribution network. The presence of stray inductance of bus bars along with the capacitance of the inverters creates a resonant circuit, which in turn can create instability in the system, so it is very critical to understand the performance and placement of Busbars in the system. As impedance is very much influenced by the geometry, shape, and materials of the bus bars, simulation tools can be utilized to accurately predict the impedance and this can be utilized to study the performance of the complete system and further optimize the busbar geometry as per system needs.

Second-order generalized integrator (SOGI) based phase-locked loops (PLLs) are used for grid voltage synchronization in single-phase grid-connected power converters. SOGI-PLLs are attractive because of the simple structure and the suitability for implementation in low-end digital controllers. In this paper, a cascaded SOGI-PLL structure is discussed, with full offset rejection capability. A systematic design procedure is proposed for this PLL minimizing the response time and unit vector harmonic distortion. This design achieves minimum settling time for a given level of frequency deviation of the grid voltage. The PLL designed using the proposed method has sufficient harmonic attenuation capability. The analytical predictions are verified experimentally.

With the increasing use of grid-connected inverters, any improvement in its reliability is desirable. Usual inverter tests focus primarily on thermal testing of semiconductor devices. However, the passive components are also sensitive to temperature. The life of dc bus electrolytic capacitors and output ac filter capacitors are temperature-dependent. Continuous operation of output filter inductors at high temperatures can cause their insulation to fail. Semiconductor thermal test procedures available in literature can be used for thermal testing of passive components also. But, the methods available in literature are regenerative and require the use of additional converters or passive systems of similar rating as the inverter under test for regeneration. A novel thermal test method is proposed for testing of passive components associated with a three-phase two-level grid-connected inverter.

Estimation of motor torque requires information of motor parameters and becomes crucial to the cases where phase inductance varies with the rotor position. Present paper proposes a simple instantaneous torque estimator for a permanent-magnet brushless dc (PM BLDC) motor drive. Proposed estimator requires information of phase currents from the current sensors and duty ratio applied to the individual phase legs of the VSI. Information of phase inductance is not required. Negligence of phase resistance reduces this estimator to a simplified one with considerable error. Applicability of this estimator even for the sinusoidal phase current supply makes it a general solution for the estimation of instantaneous motor torque for a PM BLDC motor drive. For the validation of the estimator, torque from the Simulink model of PMSM motor with trapezoidal back-emf is considered as a reference.

There are several bidirectional converters are proposed to integrate batteries, ultracapacitors, fuel cell, electric motors, etc., to control the motoring and regenerative breaking effectively in Electrical Vehicle (EV); however, in regenerative breaking the breaking action is much affected because of a) failure of regenerative breaking at lower back emf, and b) discontinuous input current at the motor end. In addition, the traditional BDC are incapable to switch the power flow direction from one to another instantaneously. Therefore, in this paper, we have proposed an instantaneous mode switching bidirectional Boost/SEPIC converter to extract maximum power even under low speed and to switch the power flow direction instantaneously from motoring mode to regenerative breaking mode and vice versa. Finally, the computation results of proposed BDC and traditional BDC are compared.
