38 results about "Trailer brake controller" patented technology

A brake controller is usually an original equipment manufacturer or aftermarket-installed device or module. It is mounted to the tow vehicle's driver's-side dashboard area, and engages a trailer's electrical braking system either time delayed, or in proportion to the tow vehicle's brake engagement when slowing down or coming to a halt. A brake controller is not needed with a trailer surge braking system unless using modern electric over hydraulic devices. The trailer in this case usually has either electric friction brakes or electric-hydraulic trailer brake actuators.

Trailer braking system and controller

A trailer brake controller and system detects absolute deceleration of a trailer by incorporating an electronic gyroscope / accelerometer combination in order to accurately calculate the deceleration subtracting out the component which is due to the force of gravity. The controller and system also receives and reads information from the towing vehicle's speed sensor. The system detects the deceleration of the trailer and sends a signal to a trailer brake activation circuit based upon an acceleration status of the trailer. In some embodiments, the system detects that the trailer is decelerating and the trailer control device sends a signal to the trailer braking system activation circuit to activate the trailer brakes. Particularly, the system is able to detect that the trailer is decelerating at an unsafe rate and to activate the trailer brakes and slow the trailer to a safe speed.

Velocity sensitive passenger vehicle trailer brake controller

A method of controlling a trailer brake system using a trailer brake controller positioned within a passenger vehicle is provided. The method includes obtaining intended braking inputs and developing an effective baseline trailer brake controller output profile based thereon. The method scales the effective baseline trailer brake controller output profile in response to an adjustable gain setting set by an operator. A vehicle velocity is obtained and used to calculate a correction factor to the effective baseline trailer brake controller output profile. The effective baseline trailer brake controller output profile is then adjusted using the correction factor to generate a corrected trailer brake controller output signal.

Trailer hold assist during standstill

A vehicle comprises a speed-sensing device outputting a signal indicating a velocity of the vehicle, a brake system outputting a signal for indicating when the brake system is being commanded to a brake torque providing state, and a trailer brake controller coupled to the speed-sensing device and the brake system. The trailer brake controller utilizes the signal of the speed-sensing device to determine when the vehicle is in a zero-velocity state and utilizes the signal of the brake system to determine when the brake system is being commanded to the brake torque providing state. The trailer brake controller transitions a brake-actuating output signal thereof from a speed-dependent zero-velocity output signal value to a trailer hold zero-velocity output signal value greater than the speed-dependent zero-velocity output signal value when it is determined that the brake system is in the brake torque providing state while the vehicle is in the zero-velocity state.

Auxiliary brake controller of automobile

The invention provides an auxiliary brake controller of an automobile. A braking controller is installed on a metal structure in front of a brake pedal at the driver position and is powered by a vehicle-mounted storage battery. A main component for achieving braking of the braking controller is composed of a direct-current motor which can achieve forward and reverse rotating and a high-intensity and low-stretching-rate flexible auxiliary brake rope. When an emergency brake button sends an emergency brake order to the braking controller, a braking controller circuit controls the direct-current motor to rotate so that the auxiliary brake rope can be wound onto a rotary table, and therefore a function of pulling the automobile brake pedal toward the position in front of a driver is achieved, and the emergency brake effect is achieved.

Truck/trailer brake control system

A braking system for a combined tractor-trailer assembly wherein a leading trailer is coupled to a towing tractor and a trailing trailer is coupled to the leading trailer. All of the wheels of the trailers are provided with brakes which may be applied and released in response to the operation of a brake control pedal operated by a driver in the tractor. The brakes also may be applied to the trailing trailer whenever the latter is parked. The brakes of the trailing trailer normally are maintained in applied condition by a spring assisted mechanism when such trailer is parked. Such mechanism normally is disabled by pressurized fluid when the trailer is in service and the pressured fluid is accessible via a valve which simultaneously enables the parking brakes and service brakes simultaneously to be coupled to and uncoupled from the pressure fluid system.
