An electro-mechanical park lock actuator includes a shaft and a circuit board. The shaft is arranged for connecting to a transmission park pawl. The circuit board includes a first non-contact inductive position sensor integrated circuit, a first trace electrically connected to the first non-contact inductive position sensor integrated circuit for determining an angular position of the shaft, and an electrical connector for connecting the circuit board to an external master controller. In some example embodiments, the electro-mechanical park lock actuator includes an electric motor drivingly connected to the shaft, and a transmission arranged in a torque path between the electric motor and the shaft.

A brake control apparatus includes: a master cylinder that outputs a brake fluid at a master pressure; a master pressure changing device that can change the master pressure irrespective of an operation of a brake pedal; a brake actuator; and a control unit that executes antilock control by reducing a brake pressure of a target wheel. Modes of the antilock control include a normal mode and a pseudo mode. In the pseudo mode, the control unit operates the master pressure changing device such that the master pressure obtains a target value of the brake pressure of the target wheel, and changes the brake pressure of the target wheel in an interlocking manner with the master pressure. When the normal mode is unavailable, the control unit executes the antilock control in the pseudo mode.

A connector in a commercial vehicle electronic braking and communication system for a trailer to connect the system to a prime mover. The connector includes an electronic control module with a first databus connection, which databus, in use, carries braking related data signals and to which a brake pressure control device is attached and a second databus connection, which second databus, in use, carries data relating to non-braking functions.

The invention relates to a control device (10) for at least one electromechanical brake booster of a brake system of a vehicle having an electronics device (32) that is designed to compare a provided sensor signal (38) relating to a differential path (d) between a valve body (12), displaced by a controlled motor, of the electromechanical brake booster and an input rod (14) of the brake system with a specified normal value range, such that, if the sensor signal (38) relating to the differential path (d) lies outside the specified normal value range, the electronics device (32) is in addition designed to define a maximum limit value for a target quantity relating to a target motor torque to be carried out by the motor, at least taking into account the sensor signal (38), in such a way that, at least during a specified time interval after the defining of the maximum limit value, at most an actual motor torque corresponding to the defined maximum limit value can be carried out by the controlled motor. The present invention also relates to an electromechanical brake booster for a brake system of a vehicle, to a brake system for a vehicle, and to a method for operating an electromechanical brake booster of a brake system of a vehicle.

A system for navigating a host vehicle may: receive, from an image capture device, an image representative of an environment of the host vehicle; determine a navigational action for accomplishing a navigational goal of the host vehicle; analyze the image to identify a target vehicle in the environment of the host vehicle; determine a next-state distance between the host vehicle and the target vehicle that would result if the navigational action was taken; determine a maximum braking capability of the host vehicle, a maximum acceleration capability of the host vehicle, and a speed of the host vehicle; determine a stopping distance for the host vehicle; determine a speed of the target vehicle and assume a maximum braking capability of the target vehicle; and implement the navigational action if the stopping distance for the host vehicle is less than the next-state distance summed together with a target vehicle travel distance.

An apparatus comprising a first circuit module and a second circuit module. The first circuit module may be configured to communicate with a vehicle over a first bus. The first circuit module generates one or more first brake control signals in response to one or more command inputs and is powered by a first power source. The first brake control signals provide primary control of hydraulic flow and pressure to control one or more brake calipers in a vehicle. The second circuit module may be configured to communicate with the vehicle over a second bus. The second circuit module generates one or more second brake control signals in response to said one or more command inputs and is powered by a second power source. The second brake control signals provide secondary control of hydraulic flow and pressure to control the one or more brake calipers. The first and the second circuit modules are fabricated on a single printed circuit board to provide redundant control of the one or more brake calipers.

An ECU operating as a vehicle control device, to be mounted on a truck tractor, has a hauling determination part and an automatic driving control part. The truck tractor is hauling/pulling a trailer. The hauling determination part detects whether the trailer is hauled by the truck tractor. The automatic driving control part switches an automatic driving mode between a first automatic driving mode and a second automatic driving mode on the basis of a detection result of the hauling determination part. The first automatic driving mode represents a situation in which the truck tractor is not hauling/pulling the trailer. The second automatic driving mode represents a situation in which the truck tractor is hauling/pulling the trailer.

A computer is programmed to determine a target brake torque that is below a preset holding brake torque and at least high enough to hold a vehicle at standstill; and upon detecting that a brake of the vehicle is applied and a speed of the vehicle is below a threshold, monotonically reduce a brake torque of the brake so that the brake torque reaches the target brake torque when the speed reaches substantially zero.

A system for navigating a host vehicle may receive an image representative of an environment of the host vehicle and determine a planned navigational action for accomplishing a navigational goal of the host vehicle. The system may identify a target vehicle, determine a current speed of the target vehicle, and assume a maximum braking rate capability of the target vehicle. The system may determine a next-state distance between the host vehicle and the target vehicle that would result if the planned navigational action was taken. The system may implement the planned navigational action if the host vehicle may be stopped using a predetermined sub-maximal braking rate within a distance that is less than the determined next-state distance summed together with a target vehicle travel distance determined based on the current speed of the target vehicle and the maximum braking rate capability of the target vehicle.

An autonomous system includes a processing device programmed to receive, from an image capture device, an image of an environment of the host vehicle; detect an obstacle in the environment, based on an analysis of the image; monitor a driver input to at least one of a throttle control, a brake control, or a steering control associated with the host vehicle; determine whether the driver input results in the host vehicle navigating within a proximity buffer relative to the obstacle; allow the driver input to cause a corresponding change in one or more host vehicle motion control systems, if the processing device determines that the driver input would not result in the host vehicle navigating within the proximity buffer relative to the obstacle; and prevent the driver input to cause the change if the driver input results in the host vehicle navigating within the proximity buffer relative to the obstacle.
