A brake-by-wire braking system for a vehicle having at least two wheels which are able to be braked is described. The braking system comprises at least two brake actuator units, each of which can be associated with one of the wheels of the vehicle which are able to be braked. The braking system further comprises a brake actuation unit for actuation by the driver for braking, having at least one sensor for detecting an activation of the brake actuation unit by the driver, an acceleration actuation unit having at least one sensor for detecting the activation of the acceleration actuation unit by the driver, and at least one electronic control unit which is adapted to operate one or both of the brake actuator units in order to bring about a braking force at an associated wheel. The control unit is adapted to operate the brake actuator units on the basis of an activation of the acceleration activation unit in the event of a fault or failure of the brake actuation unit.

The present disclosure relates to a method for cooling an endurance braking arrangement of an electric vehicle, the vehicle comprising an electrical power storage device and the endurance braking arrangement, the vehicle comprising a cabin and a fifth wheel for connection of a trailer to the vehicle, the cabin and the fifth wheel being located at an initial distance from each other; wherein the vehicle comprises a cooling system configured to receive cooling air from a position between the cabin and the fifth wheel for cooling the endurance braking arrangement of the vehicle wherein the method comprises arranging the cabin and the fifth wheel such that an increased distance between the cabin and the fifth wheel is obtained as compared to the initial distance for increasing air flow to the cooling system.

Provided is a road surface type detection device capable of distinguishing an asphalt reference road surface type from other road surface types in real time from comparison of magnitudes and frequencies of strain sensor signal waveforms that are excellent for information detection in a low-speed range. A road surface type detection device 10 that estimates a plurality of road surface types (asphalt, a gravel road, a grass road) includes at least one sensor element 1, 2, 3 that detects a physical amount of a vehicle, a road surface type estimation unit 4, and a storage unit 411 that stores output values of the sensor element 1, 2, 3 corresponding to the plurality of road surface types. Any one road surface type asphalt, a gravel road, a grass road) is estimated out of the plurality of road surface types on the basis of a magnitude of a waveform of a sensor signal output by the sensor element 1, 2, 3. It is thus possible to distinguish asphalt from other road surface types in real time.

The present disclosure provides a braking method of a vehicle, comprising: a control start determination operation of determining whether traction control system (TCS) control is needed; a required pressure calculation operation of calculating required pressures, which are required for wheel brakes to brake a vehicle, of wheels when it is determined that the TCS control is needed; a control mode determination operation of determining whether the TCS control is performed in a single wheel control mode or multi-wheel control mode; and a hydraulic pressure supply operation of supplying hydraulic pressure to a low-pressure wheel brake through valve control and supplying hydraulic pressure to a high-pressure wheel brake through pressure control in the multi-wheel control mode and supplying hydraulic pressure to any one wheel brake through the valve control in the single wheel control mode in order for the wheel brakes to reach the required pressures.

A compactor machine may include a frame, a compaction member attached to the frame, and a controller attached to the frame. The controller may be configured to detect, while the compactor machine is traveling on a paving material mat to perform compacting, an event that is to cause the compactor machine to perform a stop. The controller may be configured to identify, based on detecting the event, a zone that the compactor machine is to use to perform the stop. The controller may be configured to cause the compactor machine to travel to the zone to perform the stop.

A system for a vehicle for controlling/adjusting the wheel behaviour of at least one vehicle wheel comprises at least one unit for determining the wheel vertical force of at least two vehicle wheels which are mounted on the same axle of the vehicle. The system is adapted to determine for each of the at least two vehicle wheels at least one parameter indicative of the wheel behaviour. The system is further adapted to determine, on the basis of the wheel vertical forces determined by the unit for determining the wheel vertical force for the at least two vehicle wheels, at least the vehicle wheel with the higher wheel vertical force. The system is further adapted to set the at least one parameter indicative of the wheel behaviour determined for the at least one vehicle wheel with the higher wheel vertical force as the target value for the vehicle wheel with a lower wheel vertical force.

Operating a vehicle with an open door creates risks. Embodiments herein consider both when a vehicle is in an autonomous driving (AD) mode and a manual mode. When in AD mode, if an occupant opens the doors while the vehicle is moving, the control system may lower the speed to stop and may park the vehicle (or not park it depending upon the control policy). If an occupant opens the doors when the vehicle is stationary, the control system may keep the vehicle from rolling and from brake system failures. When the vehicle is in a manual model and a door is opened when the vehicle is moving, a warning message may be triggered; whereas, if a door is opened when the vehicle is stationary, the control system may keep the vehicle from rolling and from brake system failures. Warning messages may be triggered for different stages/conditions.

A vehicle trajectory for transitioning out of a deceleration trajectory may be determined based on predicted vehicle state(s) and/or environmental condition(s). A determination about whether to transition into the determined trajectory may be based on whether the condition that triggered the deceleration trajectory still exists, whether the determined trajectory meets safety criteria, and/or whether an alternative deceleration trajectory is warranted. The determination may be used to determine which trajectory to control the vehicle and/or to inform the vehicle's driving behavior.

A method for determining a trailer brake magnitude for a trailer brake system of a trailer being towed by a vehicle includes determining connection of a trailer to a vehicle, determining at least one trailer parameter relating to a size, shape or a weight of the trailer, and determining a trailer braking magnitude as a function of the at least one trailer parameter.
