Control method for antilock braking systems with stress sensor and measurement device of wheel operating force

摘要

An antilock braking system employing stress sensors installed in the wheel axle structure of a motor vehicle. The stress sensors measure a road surface frictional force and a braking torque. A parameter M is calculated from these measured values. An ABS control terminates a braking pressure reduction process in accordance with the change in the parameter M. Thereby, the system can preclude the locking of the wheel of the motor vehicle even when the brake is suddenly applied, can prevent the braking pressure reduction from being over controlled, and makes possible braking loss mininization.
