Автор: Tony Alan Lee
Принадлежит: Individual

A tool for pumping the brake pedal of a vehicle does not require a person in the vehicle to pump the brakes. The tool permits a person to bleed the hydraulics when doing a brake job without the need for a second person. The tool, also referred to as a pedal pumper, or a pedal pumping device, may include straps on each end for extending the tool between the steering wheel and the brake pedal. When air is supplied to the tool, the air pressure may cause the tool to extend and depress the brake pedal. When the air pressure is released, the force of the tool is released and the brake pedal is allowed to return to its un-depressed position.

The measured temperature is compared to low and high temperature thresholds defined by a thermal model, as well as to one or more other wheel speed sensor temperatures. If the measured temperature is below the low temperature threshold and substantially different than the one or more other wheel speed sensors, the brake is determined to be under-adjusted and brake force at the under-adjusted brake is increased. If the measured temperature is above the high temperature threshold and substantially different than the one or more other wheel speed sensors, then the brake is determined to be over-adjusted, and brake force is reduced or modulated at the over-adjusted brake to prevent overheating. 1.

An electromechanical brake system capable of conducting a brake pad wear check includes a structure defining a chamber, a member that rotates with a wheel, a motor mounted to the structure, a reciprocating piston, a brake pad, and a controller. The piston is driven by the motor between a variable actuated position and a retracted position. The brake pad is movably supported by the structure, operatively coupled to the piston, and adapted for braking contact with the member when the piston is in the actuated position, and spaced from the member when the piston is in the retracted position. The controller controls reciprocation of the piston between the actuated and retracted positions via energization of the motor, performs a brake pad wear check by calculating a change in a parameter associated with a change in distance between positions, and compares the change in parameter to a threshold value. 1. An electromechanical brake system configured to control the rotational speed of a wheel , the electro-mechanical brake system comprising:a structure defining a piston chamber;a member constructed and arranged to rotate with the wheel;an electric motor mounted to the structure;a piston coupled to the electric motor for reciprocation within the piston chamber between a retracted position and a variable actuated position;a brake pad movably supported by the structure, operatively coupled to the piston, and constructed and arranged to be in braking contact with the member when the piston is in the actuated position, and spaced from the member when the piston is in the retracted position, and wherein the variable actuated position is dependent upon wear of the brake pad;a controller configured to control reciprocation of the piston between the retracted position and the variable actuated position via energization of the electric motor, and to determine the variable actuated position via a first energy peak induced by the electric motor; andwherein the controller is configured ...
