How to Tell if a Vehicle Has ABS
1 Answers
Speed up to around 60 km/h and perform an emergency brake. If you feel the brake pedal and steering wheel vibrating and hear a "clicking" sound, the vehicle has ABS. Alternatively, you can look under the hood for a square-shaped component with six thin metal tubes attached to it—this is the ABS unit. Below is additional information about ABS: 1. ABS: The term "ABS" stands for "Anti-lock Braking System" in Chinese. It is a vehicle safety control system with advantages such as anti-skid and anti-lock features. ABS is an enhanced technology based on conventional braking systems and can be categorized into mechanical and electronic types. 2. Working Principle: (1) Mechanical ABS has a simple structure, primarily consisting of a mechanical valve. It uses a rubber airbag inside the valve to provide feedback on braking pressure, continuously releasing and reapplying the brakes to prevent wheel lock-up. This type is commonly found in some domestic pickup trucks and low-end buses. (2) Electronic ABS comprises components such as wheel speed sensors, wiring harnesses, a computer, an ABS hydraulic pump, and indicator lights. It sends signals to the vehicle's computer system based on factors like friction, wheel speed, turning angle, and body tilt. The computer then distributes braking force frequency, controls engine torque output, and applies varying braking forces to each wheel. This achieves scientifically balanced brake force distribution, effectively preventing issues like vehicle deviation, skidding, or fishtailing during emergency braking, thereby avoiding loss of control.
