摘要： 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.

摘要： A method to control, while driving along a curve, a road vehicle with a variable stiffness and with rear steering wheels. The method comprises the steps of: determining an actual attitude angle of the road vehicle; establishing a desired attitude angle; determining an actual yaw rate of the road vehicle; establishing a desired yaw rate; and changing, in a simultaneous and coordinated manner, the steering angle of the rear wheels and the distribution of the stiffness of the connection of the four wheels to the frame depending on a difference between the actual attitude angle and the desired attitude angle and depending on a difference between the actual yaw rate and the desired yaw rate.

摘要： An autonomous driving system for an autonomous vehicle includes an automated driving controller wirelessly connected to a towing taxi. The automated driving controller determines the autonomous driving system is non-functional. In response to determining the autonomous driving system is non-functional, the automated driving controller generates a notification indicating the autonomous driving system is non-functional. The automated driving controller receives, from the towing taxi, a current data string including a data point corresponding to a current point in time in combination with a predicted data point for each of one or more predicted points of time in the future. The current data string is compared with a previous data string recorded at a previous point in time. In response to determining the current data string matches the previous data string, the automated driving controller determines one or more driving maneuvers for the autonomous vehicle based on the current data string.

摘要： A suspension control system includes: a first electric current setting unit configured to set a first electric current based on an actual damping speed; a second electric current setting unit configured to set a second electric current based on a model damping speed; a weight coefficient setting unit configured to set a weight coefficient based on the actual damping speed; and a target electric current setting unit configured to set a sum of a first value and a second value as a target electric current of the damper, the first value being obtained by multiplying the second electric current by the weight coefficient, the second value being obtained by multiplying the first electric current by a value obtained by subtracting the weight coefficient from one. The first electric current setting unit is configured to make the first electric current smaller than the second electric current in a prescribed case.

摘要： An apparatus including a capture device and a processor. The capture device may be configured to generate pixel data corresponding to an exterior view from a vehicle. The processor may be configured to generate video frames from the pixel data, perform computer vision operations on the video frames to detect objects in the video frames and determine characteristics of the objects, detect a change in orientation of the vehicle at a first time, analyze the characteristics of the objects at a second time to determine a cause of the change in orientation of the vehicle and generate annotations for the video frames that comprise the objects determined to have caused the change in orientation of the vehicle. The second time may be earlier than the first time.

摘要： Particular embodiments may enable configuring settings of a vehicle in a designated mode. A signal to place the vehicle in a designated mode may be received. A roll angle and a pitch angle of the vehicle as parked may be assessed based on data received from a position sensor built into the vehicle. Signals to adjust an electronically controlled suspension of the vehicle to reduce the roll angle or the pitch angle so that the vehicle is level as parked may be sent based on the assessed roll angle and pitch angle exceeding a threshold value. One or more settings of the vehicle to change default operating characteristics by the vehicle while in the designated mode may be modified.

摘要： A parking assist system includes: a control device configured to execute a driving process for autonomously moving a vehicle to a target position; a steering operation member configured to receive a steering operation performed by an occupant; a vehicle state detecting device; and a notification device configured to make a notification to the occupant. In the driving process, the control device executes vehicle speed control and steering control. When, during execution of the driving process, the control device determines that the vehicle is a suspension state in which the driving process should be temporarily suspended, the control device causes the notification device to output a prescribed notification and executes a suspension process. In the suspension process, the control device executes the vehicle speed control to stop the vehicle and stops the steering control.
