Evolutionary Functional Testing of a Vehicle Brake Assistant System
نویسندگان
چکیده
The safety of today’s vehicles is one of the major concerns of the automotive industry. Modern cars are equipped more and more with vehicle assistance functions in order to increase vehicle safety. Vehicle assistance functions are realised using electronic control units (ECUs), designed for the use in a vehicle. It is of critical importance that the ECUs used in vehicles operate properly. Thus, the high quality of the ECU’s software is an important requirement for a correct vehicle assistance function. Up to now, one of the most important measures to ensure software quality is extensive testing, but testing is time-consuming and costly. This is, because testing requires the definition and execution of test cases and the evaluation of the test results. Manual definition of test cases is difficult and time-consuming. Evolutionary testing has the potential to automate test case design. A test environment for an evolutionary functional test of a brake assistance function will be described in this work. First, the brake assistance function is described, which is subject to testing as application in a vehicle. Second, an introduction to evolutionary testing is given. Then, the theory and architecture for an evolutionary functional test of a brake assistance function is presented. The practical experiments which were carried out and the obtained results are shown. Finally, a conclusion is drawn and some prospects for possible future work are given.

In driving and when you brake, a lot of energy is dissipated to stop the car; especially in urban areas where the vehicle is driving in a stop-and-go pattern. This energy, which is dissipated by the brake pads, can be stored in the vehiclechr('39')s battery. In Hybrid and Electric Vehicles, a regenerative brake can be used alongside the mechanical brakes to regenerate some energy while braking....

A unique decoupling feature in frictional disk brake mechanisms, derived through kinematic analysis, enables modularised design of an Anti-lock Braking System (ABS) into a sliding mode system that specifies reference brake torque and a tracking brake actuator controller. Modelling of brake actuation, vehicle dynamics, and control design are described for a scaled vehicle system. The overall con...
