  • Patent number: 10967839
    Abstract: A vehicle control system of a vehicle includes a trailer brake control electronic control unit (ECU), which in turn includes a trailer brake output circuit. The trailer brake control ECU is configured to receive an electronic parking brake (EPB) state flag and a vehicle acceleration message. The dynamic EPB state flag indicates one of an ON state and an OFF state of a dynamic EPB, and the vehicle acceleration message indicates an acceleration of the vehicle. The trailer brake control ECU outputs, via the trailer brake output circuit, a trailer brake signal based on the acceleration of the vehicle indicated by the received vehicle acceleration message in response to determining that the received dynamic EPB state flag indicates the ON state.

  • Publication number: 20200247371
    Abstract: A system for a vehicle and a trailer connected to the vehicle is provided. The system includes a trailer brake output circuit configured to output a trailer brake output signal, and an electronic control unit. The electronic control unit is configured to determine whether a value of a yaw rate of the trailer connected to the vehicle becomes greater than a threshold value, change a yaw rate oscillation counter in response to determining that the value of the yaw rate of the trailer becomes greater than the threshold value, instruct the trailer brake output circuit to output the trailer brake output signal to the trailer in response to the yaw rate oscillation becoming a first value, and activate trailer sway control in response to the yaw rate oscillation becoming a second value. The second value is greater than the first value.

  • Publication number: 20200247373
    Abstract: A system for controlling a trailer brake output circuit includes an electronic control unit having one or more processors and one or more memory modules. The trailer brake output circuit is configured to output a trailer brake output signal. Machine readable instructions cause the electronic control unit to: receive a signal from a vehicle stability control system indicating that a vehicle stability control flag is set, generate the trailer brake output signal in response to the vehicle stability control flag being set such that the trailer brake output signal ramps up to a target value over a predefined period of time, maintain the trailer brake output signal at the target value while the vehicle stability control flag is set, and output the trailer brake output signal such that the trailer brake output signal ramps down from the target value when the vehicle stability control flag changes from set to not set.

  • Publication number: 20190299735
    Abstract: A damper assembly to harvest energy from road deflections including a housing with a first shell, a second shell affixed to the first shell and to a vehicle body, a generator assembly with a first generator nested in the first shell, and a second generator nested in the second shell, a ball screw crossing the housing and with a first terminal portion that protrudes from the first shell and affixed to a wheel assembly of the vehicle, a second terminal portion that protrudes from the second shell, and a central portion extending between the first terminal portion and the second terminal portion, wherein the central portion actuates the first generator to provide a first electrical current when the wheel assembly is displaced in a first direction and the second generator to provide a second electrical current when the wheel assembly is displaced in a second direction.

  • Patent number: 10119985
    Abstract: A smart sensor system and method for a vehicle are described. The smart sensor includes at least one sensing element installed on a suspension of the vehicle and coupled with a wheel of the vehicle, and a digital signal processing circuitry configured to receive signal from the at least one sensing element in the form of a digital signal, correlate the digital signal to an air gap data, and determine a vehicle speed, a vehicle acceleration, a suspension condition, a tire condition, a brake condition, a wheel condition, and a road condition.
