1. Under the conditions of the training room, it can simulate the ABS+EBD functions ;
2. To enable students to have an intuitive understanding of the control switches, buttons, sensors and actuators related to the ABS control unit and the circuit schematics;
3. Through operation, students will have an in-depth and detailed understanding of the working principles and processes of ABS and EBD as well as the specific phenomena they manifest;
II. Features
1. ABS anti-lock function: adjust the wheel speed of the four wheels to make them all exceed or equal to 20KM/H, step on the simulated brake pedal, the ABS scavenge pump works, the valve needle in the valve body moves, and the four wheel brake indicators on the panel light up at the same time, and the wheel speed decreases. If the brake pedal is not released, the vehicle speed will eventually drop to zero and the wheels will stop running;Releasing the brake pedal, and the wheels will start running again;
2. Conventional braking: adjust the wheel speed of the four wheels to less than 20KM/H, press the brake pedal, ABS scavenge pump does not work, the valve needle in the valve body does not move, the four wheel brake indicators on the panel do not light up and the wheel speed decreases. If the brake pedal is not released, the vehicle speed will eventually drop to zero and the wheels will stop running. Releasing the brake pedal and the wheels will start running again.
3. EBD braking force distribution function: When the front and rear axles are subjected to uneven gravity, before the ABS takes effect, the system actively adjusts the wheel speeds of the front and rear axles to make them close to the same. When the ABS takes effect, the front and rear wheels can be braked and stopped at the same time to avoid forward grabbing and backward leaning;
4. Braking: When the system is braking, the wheel being braked will slow down, the speedometer value will decrease, and the brake indicator light of the corresponding wheel will light up at the same time so as to have a direct perception of braking effectiveness.
5. Set and clear faults for each sensor part:
1) A fault is set on the brake pressure sensor, so ABS does not work;
2 ) Perform a fault setting on the wheel speed sensor, ABS does not work but EBD works ;
6. Active intervention in the running light demonstration:
1) Boost: In a static state, press the active intervention button, and the running light indicates the direction of the oil path during the boost process;
2) Maintaining pressure: Press the active intervention button again, and the running light indicates the direction of the oil path during the pressure maintaining process;
3) Decompression: Press the active intervention button again, and the running light indicates the direction of the oil path during the decompression process;
4) Conventional braking: Press the active intervention button again, and the running light indicates the direction of the oil path during the conventional braking process;
5) Demonstration completed: Press the active intervention button again, the running light will turn off and return to the static state;
7. Signal detection: Use a multimeter to detect the voltage of each signal detection terminal, and use an oscilloscope to detect the waveform of each signal detection terminal;
8. OBD II diagnostic socket is equipped, which enable to use the car diagnostic instrument(Scanner) to read the ABS control unit fault code and data stream.
