Subject syllabus:
1.Measuring wheel speed (measuring directly on the sensor ABS, reading wheel speed from the CAN bus, conversion of measured pulses to wheel speed and vehicle speed).
2.Measurement of ABS, wheel speed, acceleration, pressure in the brake circuit.
3.Measurement permitted braking force (by TÜV - measuring the force on the pedal and longitudinal acceleration).
4.Measuring braking distance (deceleration from the accelerometer, speed sensors, calculation).
5.Measurement of torque on the semi-axes.
6.Measurement 0-50,100 acceleration from wheel speed and GPS.
7.Measurement of parameters for the virtual differential and skid detection (measuring wheel speed depending on the steering angle, measuring the turning radius of the vehicle depending on the steering angle).
8. Measuring antiskid, wheel speed and their derivatives and reduced performance in a straight line and when turning.
9.Measuring the efficiency of the brakes, wheel speed, acceleration,discs temperature , etc.
10.Measurement of passive resistances, sailing of vehicle.
11.Measuring yaw and its comparison with a turning of the steering wheel, the detection of skid.
