  • Patent number: 10196089
    Abstract: A method of controlling a backing system for a vehicle and trailer assembly comprises initiating a backing system mode with an electronic control unit (ECU) for the backing system when a start system input is received from a control device. At least one input is received by the ECU from the control device which includes information about a desired vehicle action. The ECU interprets from the at least one input the desired vehicle action and calculates a required vehicle response to achieve the desired vehicle action. The ECU then sends a request to at least one vehicle system to perform the calculated vehicle response.

  • Patent number: 9637102
    Abstract: A brake system includes a brake pedal for actuating a master cylinder having two pistons and corresponding pressure chambers, where the system can be operated in a brake-by-wire mode and also a fallback mode. The system also includes a first electrically controllable pressure source and a second electrically controllable pressure source. The first and second electrically controllable pressure sources each have corresponding output flows that are connected together. The second electrically controllable pressure source can therefore provide output volume flow in the event the first electrically controllable pressure source fails.

  • Patent number: 9415758
    Abstract: The invention relates to a method for providing haptic information to the driver of a motor vehicle, equipped with a brake-by-wire brake system, about the operating state of the brake system, in which method the brake pedal characteristic is generated by a pedal travel simulator, in the form of a functional relationship between the brake pedal opposing force and the brake pedal travel, and is modified as a function of an operating state. In order to provide the driver with the haptic information channel via which electronically controlled information can be communicated to the driver during braking, without the impression of a defect arising, the invention proposes that a basic brake pedal characteristic is generated by a passive simulator spring which assigns pedal travel, on which pedal return travel transporting the haptic information is superimposed, to a given pedal force in an unchanging, constant relationship.

  • Patent number: 9315180
    Abstract: A brake system for motor vehicles, which brake system can be actuated both by the vehicle driver and also independently of the vehicle driver in a “brake by wire” operating mode, is preferentially operated in the “brake by wire” operating mode, and can be operated in at least one fall-back operating mode in which only operation by the vehicle driver is possible. The brake system has inter alia an electrohydraulic pressure generating device (5) which outputs a brake system pressure, and a pressure modulation unit which has one inlet valve (6a-6d) and one outlet valve (7a-7d) per wheel brake (8, 9, 10, 11) for setting wheel-specific brake pressures derived from the brake system pressure, wherein the inlet and outlet valves (6a-6d, 7a-7d) output or transmit the brake system pressure when in the non-actuated state.

  • Patent number: 9145121
    Abstract: A method for monitoring a brake system for motor vehicles. The system can be actuated both by a vehicle driver and independently of the vehicle driver in what is known as a brake-by-wire mode. The hydraulic actuation device can be actuated by means of a brake pedal and has a main brake cylinder to which wheel brakes are connected, at least two brake circuits, a simulation device, which comprises at least one elastic element and gives the vehicle driver a comfortable pedal feeling, an electrically controllable pressure-providing device, which is formed by a cylinder/piston assembly, the piston of which can be actuated by an electromagnetic actuator, wherein the first measurement variable (PDBE) characterizing a position of the piston is detected. The detected measurement value of the first and second measurement variable (SDBE, PDBE) are compared to a predetermined characteristic map of the first and second measurement variables in order to monitor a functional status of the brake system.
