Abstract
An electric braking system and methods for a utility vehicle is provided. The system includes a rotor coupled to a rear axle of the utility vehicle. A caliper is electrically controlled to provide stopping force to the rotor. A spring is pre-loaded to actuate the caliper when additional stopping force is needed. A controller controls the activation of the caliper by generating an electrical braking signal to control operation of the caliper based on a brake position signal generated from a brake pedal position sensor.
Claims22
A method of providing electric braking for a utility vehicle, comprising:
- providing an electric brake assembly including a rotor that is coupled to a rear axle shaft of the utility vehicle, an electric caliper that supplies stopping force to the rotor, and a spring that is pre-loaded to provide an alternative stopping force to the rotor;
- determining an electrical braking signal based on the brake position signal generated from a brake position sensor coupled to a brake pedal of the utility vehicle;
- and
- controlling operation of the electric caliper based on the electrical braking signal.
An electric braking system for a utility vehicle, comprising:
- a rotor coupled to a rear axle of the utility vehicle;
- a caliper that is electrically controlled to provide stopping force to the rotor;
- a spring that is pre-loaded to actuate the caliper when additional stopping force is needed;
- and
- a controller that controls the activation of the caliper by generating an electrical braking signal to control operation of the caliper based on a brake position signal generated from a brake pedal position sensor.
The system of claim 111 the controller configured to regulate the electrical braking signal to electric caliper brake utilizing a transistor circuit.
A utility vehicle, comprising:
- a left electromechanical brake assembly coupled to a left side of a rear axle of the utility vehicle;
- a right electromechanical brake assembly coupled to a right side of the rear axle;
- a brake pedal assembly that includes a brake position sensor and a brake pedal and the brake position sensor generates a brake position signal based on a position of the brake pedal;
- and
- a controller that controls the left electromechanical brake assembly and the right electromechanical brake assembly based on the brake position signal.
