Automated warning system to detect a front vehicle slips backwards
11440471 · 2022-09-13 · ·

In one embodiment, a system perceives an environment surrounding an ADV including a vehicle in front of the ADV. The system determines whether the vehicle in front is slipping backwards based on the perception. The system determines whether the vehicle in front is situated on a road with a slope based on map information. The system determines whether a tail light or a brake light of the vehicle in front is turned on based on the perception. If it is determined that the vehicle in front is situated on a sloped road, is slipping backwards, and the tail light or the brake light is not turned on, the system calculates a time to impact or a distance to impact based on the distance and speed of the vehicle in front.

CONTROLLING MOVEMENT OF A VEHICLE

Apparatus for controlling movement of a vehicle, a system and vehicle comprising the apparatus, and a method for controlling the movement of a vehicle are disclosed. The apparatus comprises a controller configured to receive first signals from a receiving means in dependence on received transmitted signals from a remote control device indicating a requested motion of a vehicle and to receive second signals indicative of a value of traction of the vehicle. A maximum speed value for the vehicle is determined in dependence on the value of traction of the vehicle and/or on one or both of the detected pitch and roll angles of the vehicle. The controller provides an output signal for controlling speed of the vehicle based on the requested motion. The output signal is limited dependent upon the maximum speed value determined by the controller.

Method and vehicle for activating an autonomous braking maneuver
11414060 · 2022-08-16 · ·

Embodiments herein relate to a method performed by an autonomous vehicle for activating an autonomous braking maneuver of the autonomous vehicle having an autonomous drive system. The autonomous vehicle detects at least one user initiated request for an autonomous braking maneuver of the vehicle when the vehicle is in a first autonomous drive mode at a speed. The autonomous braking maneuver is at least one of: speed reduction or stop. When the request has been detected, the autonomous vehicle activates the autonomous braking maneuver of the vehicle which reduces the speed and/or brakes the vehicle to a stop.

20220097662 · 2022-03-31 · ·

The driving force control device includes: a requested driving force calculation unit configured to calculate requested driving force requested to the vehicle, in a coasting state where neither an accelerator operation nor a brake operation is performed by a driver; a power train control unit configured to control a gear ratio of the power train on the basis of the requested driving force and driving force that is achieved by the power train in the coasting state; a braking force calculation unit configured to calculate braking force required for achieving the requested driving force, when the requested driving force is smaller than driving force that is achieved by the power train at a gear ratio set by the power train control unit; and a brake control unit configured to cause the brake to generate the braking force calculated by the braking force calculation unit.

Braking force control apparatus for vehicle

A braking force control apparatus is provided which has an upstream braking actuator for generating an upstream pressure common to four wheels, a downstream braking actuator individually controlling braking pressure supplied to braking force generating devices of the wheels using the upstream pressure, and a control unit. When the downstream braking actuator is abnormal and the upstream pressure can be supplied to the braking force generating devices, but a braking pressure of any one of the wheels cannot be normally controlled, the control unit selects a control mode on the pressure increasing side out of the front wheel control modes, selects a control mode on the pressure increasing side out of the rear wheel control modes, selects a control mode on the pressure decreasing side out of the two selected control modes as a prescribed control mode, and controls the upstream pressure in the prescribed control mode.

Vehicle control device

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.

ELECTRIC BRAKE DEVICE

An electric brake mechanism includes a piston (6D) propelled by a rotation-linear motion mechanism (8) driven by an electric motor (7A). The piston (6D) is configured to press brake pads (6C) against a disc rotor (4), and to hold the brake pads (6C) at a pressing position by stopping the electric motor (7A). A parking brake control device (24) is configured to determine, when a request (application command) to hold the brake pads (6C) is made, a judgment timing for judging whether to stop the electric motor (7A) based on a change trend of a current value of the electric motor (7A). When the judgment timing is reached, the parking brake control device (24) judges whether or not to stop the electric motor (7A).

An object-detection system for an automated vehicle includes an object-detector, a receiver, and a controller. The object-detector detects detectable-objects proximate to a host-vehicle. The receiver receives an indication of an object-presence from other-transmitters proximate to the host-vehicle. The controller is in communication with the object-detector and the receiver. The controller is configured to operate the host-vehicle to avoid interference with a hidden-object when the hidden-object is not detected by the object-detector and the object-presence is indicated by at least two instances of the other-transmitters.
