SYSTEMS AND METHODS FOR HANDLING AN OPEN DOOR OF A VEHICLE
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.
Parking method and apparatus
The method includes: when the vehicle satisfies a one-pedal activating condition, controlling the vehicle to enter a one-pedal-function activating mode; when the vehicle enters the one-pedal-function activating mode and satisfies a parking-controlling-function activating condition, acquiring current-vehicle-speed information, road-slope information and a first electric-motor recovering torque; based on the current-vehicle-speed information and the road-slope information, calculating to obtain a parking torque; acquiring a first torque difference between the parking torque and the first electric-motor recovering torque; and performing pressure buildup to the vehicle based on the first torque difference, to control the vehicle to complete a parking operation.
METHOD AND CONTROL ARRANGEMENT FOR CONTROLLING BRAKING OF A VEHICLE
The present invention relates to a method performed by a control arrangement for controlling braking of a vehicle comprising: a service brake system and at least one auxiliary brake system for applying a brake torque to at least driven wheels of the vehicle, driver maneuverable means for requesting brake torque from the service brake system, the method comprising, when a brake torque is requested by the driver, and when a temperature of a friction brake of the service brake system increases, or is expected to increase: reducing brake torque applied by the service brake system, and increasing brake torque applied by the at least one auxiliary brake system such that the total resulting brake torque corresponds to the driver requested brake torque. The invention also relates to a control arrangement, a computer program, a computer-readable medium and a vehicle comprising a control arrangement.
METHOD AND CONTROL ARRANGEMENT FOR CONTROLLING A BRAKE SYSTEM IN A VEHICLE
A method to control a brake system in a vehicle, the vehicle comprising an auxiliary brake system configured to apply a brake force to at least one first wheel of the vehicle and a foundation brake system configured to apply a brake force to at least one second wheel of the vehicle. The method comprises, when a first brake force is or is to be applied to the vehicle by means of the auxiliary brake system and when an indication of an instability condition associated with a coming road section is detected initiating a transfer of at least a part of the first brake force applied to the vehicle by the auxiliary brake system to, instead, be applied by the foundation brake system prior to reaching the coming road section to overcome the detected instability condition, such that applied brake force may be distributed over additional wheels to increase stability.
Management of vehicle braking
A method, and associated system and computer program product, for managing braking of a moving vehicle. A speed and deceleration of the moving vehicle are monitored. External and/or internal conditions relating to the moving vehicle and/or the vehicle's driver are detected. A hardware processor: calculates a braking distance for the moving vehicle for the detected external and/or internal conditions from the monitored speed and deceleration of the moving vehicle; determines a spacing distance between the moving vehicle and a second vehicle ahead of the moving vehicle; adds a cascading response distance to the calculated braking distance for a third vehicle ahead of the second vehicle; and determines that the calculated braking distance is greater than the determined spacing distance. An output is generated in response to the determination that the calculated braking distance is greater than the obtained spacing distance.
ELECTRONIC PARKING BRAKE SYSTEM AND CONTROL METHOD THEREOF
Disclosed is an electronic parking brake system including: an electronic parking brake configured to generate a braking force in a vehicle by a motor; and a controller configured to operate or release the electronic parking brake, wherein the controller is configured to collect, according to detection of a driver's intention to park, at least one of vehicle information, surrounding environment information, or parking mode setting information of the vehicle; set a target braking force for parking the vehicle based on the at least one of the vehicle information, the surrounding environment information, or the parking mode setting information, and control a parking operation of the vehicle to generate the target braking force by operating the electronic parking brake.
METHOD FOR BRAKING A TRACTOR-TRAILER
A method of braking a tractor-trailer includes sensing, autonomously, a braking event, the braking event being indicative of a requirement for braking the tractor-trailer and actuating a trailer brake valve of a trailer of the tractor-trailer to apply trailer brakes prior to actuating a tractor brake valve of a tractor of the tractor-trailer to apply tractor brakes and to apply trailer brakes. Actuating the trailer brake valve of the trailer of the tractor-trailer occurs in response to the sensing of the braking event.

Road surface detection using anti-lock braking system pressure sensor
A road surface detection system, in one example the system includes a hydraulic unit of an anti-lock braking system, the hydraulic unit including a preload adjuster, and a plurality of pressure sensors configured to generate pressure sensor data. The system also includes a controller configured to receive the pressure sensor data from the plurality of pressure sensors, determine a target preload pressure level, compare the pressure sensor data with the target preload pressure level to calculate a pressure differential between the pressure sensor data and the target preload pressure level, determine a road surface based upon the calculated pressure differential, and regulate the preload adjuster to change the pressure within the hydraulic unit based upon the road surface.
Vehicle Control Method and Apparatus, Vehicle, and Storage Medium
A vehicle control method includes collecting control-related information, determining a road condition scenario based on the control-related information, determining, based on the road condition scenario, a preset braking control parameter set corresponding to the road condition scenario, and performing control configuration based on the determined preset braking control parameter set.
