What does eABS brake mean?
1 Answers
So-called eABS does not actually have the real ABS anti-lock function, but is actually the so-called "e-brake", which is an electric brake. The ABS system mainly consists of 4 parts: wheel speed sensor, electronic control unit ECU, hydraulic unit, and ABS fault light. The wheel speed sensor detects the motion state of the wheels and sends out a sine wave electronic pulse AC signal, which is then processed by the modulator, converting the pulse into a digital signal and transmitting it to the electronic control unit. The electronic central control unit ECU receives the input signal from the wheel speed sensor, calculates the wheel speed, vehicle speed, and slip rate based on this parameter, judges the wheel state according to the slip rate, and issues control commands to the hydraulic unit. The hydraulic unit adjusts the pressure of the brake pipeline according to the control commands, and the adjustment process includes pressure holding, pressure increasing, and pressure reducing. The ABS fault light is used to alert the driver whether the system has a fault.
