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 (36) of a motor vehicle. The stress sensors (29-32) measure a road surface frictional force (F) and a braking torque (T). A parameter calculating means (3) calculates a parameter M from these measured values. An ABS control means (8) 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 (39) of the motor vehicle even when the brake is suddenly applied, can prevent that an "over control" of the braking pressure reduction occurs and makes it possible to minimize any braking loss. <IMAGE>
