A vehicle control device includes a processor configured to execute computer-readable instructions to perform. The processor is configured to acquiring a state of a first battery and a state of a second battery, acquiring motor power that is consumed by a motor that outputs motive power for traveling, detecting a rotation state of a drive wheel driven by the motor, calculating a first upper power limit value on the basis of the state of the first battery, calculating a second upper power limit value on the basis of the state of the second battery, and controlling the amount of electric power that is supplied from each of the first battery and the second battery to the motor on the basis of the calculated first and second upper power limit values. The controlling the amount of electric power includes determining whether to compensate for the motor power equivalent to the amount of change or limit compensation for the motor power equivalent to the amount of change when the change in the rotation state satisfies a reference condition.

A working machine includes a machine body, a steering device capable of changing an orientation of the machine body, a first wheel on the machine body, a second wheel on the machine body and separated from the first wheel in a machine-body width direction, a rotational difference generator to cause a rotational difference between the first and second wheels and that is a braking device, and a controller configured or programmed to include a first control unit to set a steering angle of the steering device based on a planned traveling route, and a second control unit to control the rotational difference generator based on the planned traveling route to cause a rotational difference between the first and second wheels. Based on the planned traveling route, the second control unit is configured or programmed to cause the braking device to perform setting about braking of either the first or second wheels by performing pumping control.

A vehicle control device having a prime mover, a first rotating member which is rotated by power of the prime mover, and a second rotating member which is connected to the first rotating member and which rotate a drive wheel, includes a deriving unit which derive a prime mover request output that is an output requested by the prime mover in accordance with a request output to the drive wheel, and a control unit which increase or decrease a rotation speed of the prime mover between a lower limit rotation speed and an upper limit rotation speed in accordance with a change in a rotation speed of the drive wheel. The control unit increases or decreases the rotation speed of the prime mover without changing a power output by the prime mover or an output of the first rotating member in accordance with the prime mover request output.

An electrical passenger car, the electrical passenger car including: at least two electrically driven motors; motor control electronics; sensors; and wheels, where the wheels include a first front wheel and a first back wheel, where the first back wheel has a radius at least 15% greater than a radius of the first front wheel, and where the motor control electronics control the at least two electrically driven motors to provide a greater torque to the front wheel than to the back wheel, or where the motor control electronics control the at least two electrically driven motors to provide a greater torque to the back wheel than to the front wheel.

A method (A) for the traction-related control of a drive-train of a working machine (1) having a drive unit (2), a transmission (3), a control unit (10) and first and second vehicle axles (7, 9) each supporting wheels (6, 8). At least one of the vehicle axles (7, 9) being driven, and following the entry of a drive requirement relating to a driving speed, wheel slip is iteratively reduced by adapting a rotational speed of the wheels (6, 8) of the driven vehicle axle (7, 9).

The present invention obtains a controller and a control method capable of appropriately stabilizing a posture of a straddle-type vehicle.

In the controller and the control method according to the present invention, when the straddle-type vehicle jumps, automatic posture control for controlling the posture of the straddle type vehicle by increasing or reducing a rotational frequency of a wheel is executed in accordance with posture information at the time when the straddle-type vehicle jumps. Furthermore, in the case where it is determined whether a driver has intention to control the posture of the straddle-type vehicle at the time when the straddle-type vehicle jumps without relying on the automatic posture control and where it is determined that the driver has the intention, the automatic posture control is prohibited.

A system for controlling turning of vehicle may include a steering angle detection sensor; a front inner wheel speed detection sensor detecting a front inner wheel speed; a front outer wheel speed detection sensor detecting a front outer wheel speed; a rear outer wheel speed detection sensor detecting a rear outer wheel speed based on a turning direction; and a braking controller receiving detection signal of the steering angle detection sensor to determine that the vehicle turns, estimating the rear inner wheel speed in the turning direction based on detection signals of the front inner wheel speed detection sensor and the front outer wheel speed detection sensor and detection signal of the rear outer wheel speed detection sensor, and executing a mode for decreasing the estimated speed as compared to the rear outer wheel speed, as a control mode for reducing a minimum rotation radius at the time of turning.

An operating system for an automated vehicle includes a failure-detector and a controller. The failure-detector detects a component-failure on a host-vehicle. Examples of the component-failure include a flat-tire and engine trouble that reduces engine-power. The controller operates the host-vehicle based on a dynamic-model. The dynamic-model is varied based on the component-failure detected by the failure-detector.

In a method for ascertaining the coefficient of friction between a vehicle wheel and the roadway, at least one active vehicle unit influencing the longitudinal dynamics of the vehicle is controlled during the trip in such a manner, that the longitudinal wheel force acting upon at least one vehicle wheel is increased, and/or the contact patch force of the wheel is decreased, while the characteristic of the sum of all of the longitudinal forces acting upon the vehicle remains unchanged.

A vehicle comprises an autonomous driving system and a vehicle platform that controls the vehicle in response to a command received from the autonomous driving system. In the vehicle, when a first signal indicates an autonomous mode, the vehicle platform performs a shift change requested through a first command only while the second signal indicates a standstill.
