The present disclosure includes a system, method, and device related to controlling brakes of a towed vehicle. A brake controller system includes a brake controller that controls the brakes of a towed vehicle based on acceleration. The brake controller is in communication with a speed sensor. The speed sensor determines the speed of a towing vehicle or a towed vehicle. The brake controller automatically sets a gain or boost based on the speed and acceleration.

A sensor device for detecting a displacement of a master brake cylinder piston of a master brake cylinder situated on and/or in a hydraulic unit includes: a sensor element; an evaluation electronics system; a first molded part on or in which the at least one sensor element is situated, the first molded part including at least one first electrical contact element; and a second molded part. The at least one first electrical contact element contacts at least one second electrical contact element of the second molded part which is at least partially introduced into the second opening.

A machine includes: an axle having wheels mounted to it; a brake system configured to provide service braking to the wheels; a brake pedal operatively connected to the brake system to provide a braking power to the wheels in proportion to the position of the brake pedal; a pedal sensor operatively connected to the brake pedal to sense the position of the brake pedal; a retarder system configured to selectively slow the wheels down; a speed sensor operatively connected to the machine to detect a speed associated with the machine; a controller operatively connected to the speed sensor, brake pedal position sensor, and retarder system wherein the controller is configured to operate the retarder system based on signals received from the speed sensor and brake pedal position sensor. A method for providing an indication to an operator may also be included.

Disclosed is a control method for a motor of an electronic brake. The control method for a motor of an electronic brake includes: a stop mode-starting step of starting a stop mode when a vehicle is stopped by a brake; an electrical angle-measuring step of measuring an electrical angle of a motor providing pressure to the brake in the stop mode; an electrical angle-calculating step of calculating a changed electrical angle using a predetermined electrical angle change and the electrical angle of the motor measured in the electrical angle-measuring step; and a motor-controlling step of controlling a current flowing to the motor in accordance with the changed electrical angle. Therefore, it is possible to keep a vehicle stopped, prevent a high current from flowing at any one phase of the motor, and prevent the motor from burning.

A supplemental braking system for controlling the braking of a towed vehicle. a supplemental brake application apparatus, a supplemental braking monitor, and a transmitter. The supplemental brake application apparatus is configured to be installed in a towed vehicle. The supplemental brake application apparatus is configured to move a brake pedal of the towed vehicle between a first position and a second position. The supplemental braking monitor is also configured to be installed in the towed vehicle. The supplemental braking monitor includes a proximity sensor configured to produce a proximity detection signal, and a mounting plate configured to secure the proximity sensor in a position such that the proximity sensor can detect movement of the brake pedal. The proximity detection signal is based at least in part on movement of the brake pedal. The transmitter is configured to send a brake status signal to a towing vehicle.

A method for operating a hill hold controller of a motor vehicle including at least one parking brake. The parking brake is disengaged according to an actuation of a gas pedal of the motor vehicle. The disengagement of the parking brake is released according to a variable representing a road gradient. The release to disengage the parking brake is granted, independently of the variable and/or the availability of the variable, when the gas pedal of the motor vehicle reaches or exceeds a predefinable release position by way of the actuation thereof.

A vehicle brake control apparatus according to the invention stops an activation of a brake device when a person exists outside of a braking area. The apparatus determines whether or not the person exists outside of the braking area on the basis of a moving direction and a moving amount of at least one characteristic point included in a landscape image captured by a camera device when a person image included in the landscape image cannot be detected by a pattern matching technique.

A vehicle speed control system for a vehicle having a plurality of wheels, the vehicle speed control system comprising one or more electronic control units configured to carry out a method that includes applying torque to at least one of the plurality of wheels, detecting a slip event between any one or more of the wheels and the ground over which the vehicle is travelling when the vehicle is in motion and providing a slip detection output signal in the event thereof. The method carried out by the one or more electronic control units further includes receiving a user input of a target speed at which the vehicle is intended to travel and maintaining the vehicle at the target speed independently of the slip detection output signal by adjusting the amount of torque applied to the at least one of the plurality of wheels.

A braking control method includes steps of: (i) confirming whether to enter a blending section where regenerative braking torque is reduced and friction braking torque is increased; (ii) determining a target reduced deceleration by a controller upon entering the blending section; (iii) reducing braking torque of a vehicle in response to the determined target reduced deceleration; and (iv) returning the braking torque of the vehicle to driver's requested braking torque when the vehicle is being stopped.

A brake system for actuating a plurality of wheel brakes in a normal non-failure braking mode and in a backup braking mode includes an MC-type power transmission unit having a first electric motor. An iso/dump control valve arrangement is associated with each wheel brake of the plurality of wheel brakes. A pump piston is associated with at least one wheel brake of the plurality of wheel brakes. The pump piston is driven by a second electric motor for selectively providing pressurized hydraulic fluid to the iso/dump control valve arrangement. At least one electric brake motor is operative to selectively drive a selected wheel brake. A first electronic control unit is operative to selectively control the first electric motor. A second electronic control unit is operative to selectively control the second electric motor. A third electronic control unit is operative to control the at least one electric brake motor.
