A method of controlling a vehicle when the vehicle passes over a speed bump, may include: dividing sections of the road into a first section within a first time period before the front wheel of the vehicle collides with the speed bump, a second section while the front wheel collides with the speed bump, a third section within a second time period before the rear wheel collides with the speed bump, and a fourth section while the rear wheel collides with the speed bump; and controlling and distributing at least one of suspension damping force, driving power and braking force to the front wheel and the rear wheel for each of the first section, the second section, the third section and the fourth section to reduce the amount of impact to be applied when the vehicle collides with the speed bump and to reduce a vertical motion of the vehicle that occurs while the vehicle goes over the speed bump.

A vehicle speed control system that carries out a method of: automatically causing application of positive and negative torque to one or more wheels of a vehicle to cause a vehicle to travel in accordance with a target speed value v_target; controlling a rate of change of speed of the vehicle by application of positive and negative torque to one or more wheels; and receiving information relating to a terrain response mode in which the vehicle is configured or an amount of drag imposed on a vehicle. The system is configured to control the rate of change of speed in dependence at least in part on the terrain response mode, the amount of drag imposed on the vehicle, or both.

A road surface evaluation apparatus includes a microprocessor configured to perform: acquiring driving information of each of a plurality of vehicles, including a position and an acceleration of each of the plurality of vehicles while traveling, and a map information including road information on a road where the plurality of vehicles travel; evaluating a surface roughness of the road based on accelerations of the plurality of vehicles acquired in the acquiring within a predetermined period and, when a degree of accumulation of the accelerations of the plurality of vehicles acquired within the predetermined period is less than a predetermined value, evaluating the surface roughness by complementing the acceleration of the plurality of vehicles acquired before the predetermined period; and outputting information on the surface roughness evaluated in the evaluating in association with the road information acquired in the acquiring.

A method for detecting and processing the carriageway condition of a carriageway on which a vehicle is driven, by means of at least one noise sensor provided on the vehicle, in particular by means of at least one mechanical vibration sensor, wherein noise signals travelling through the vehicle are sensed by a noise sensor and conclusions as to the carriageway condition are drawn from the sensed noise signals. According to said method, the section of route on which the vehicle is currently being driven is determined, the determined carriageway condition is assigned to the section of route, said section of route and the carriageway condition that has been determined and assigned to the section of route are transmitted to a computer network, in particular to a cloud-based computing service, and the information relating to the carriageway condition assigned to a section of route is made available via the computer network.

A method for operating a motor vehicle by detecting a destination input by a motor vehicle occupant; and determining which residual range of the motor vehicle will be indicated at the destination. If the determined residual range is less than a predetermined threshold value, the motor vehicle is operated in a consumption optimizing mode during which the motor vehicle is operated to carry out automatic measures for reducing the consumption of the motor vehicle until reaching the destination.

A control system configured to accurately determine a condition of a road surface on which a vehicle travels. A learned model estimates the road surface condition based on the travelling data collected during propulsion of the vehicle, and a controller determines the road surface condition based on the road surface condition estimated by the learned model.

A vehicle includes wheels, brakes, and a controller. The wheels are configured to propel the vehicle. The brakes are configured to generate a braking torque at the wheels. The controller is programed to, in response to (i) a commanded braking torque and (ii) a relative jounce between two of the wheels exceeding a threshold, operate the brakes to increase the braking torque to less than the commanded braking torque. The controller is further programed to, in response to (i) the commanded braking torque and (ii) a droop of at least one of the wheels exceeding a threshold, operate the brakes to increase the braking torque to less than the commanded braking torque.
