An oscillation-type vehicle includes a front vehicle body that suspends a front wheel in a steerable manner, a rear vehicle body that suspends left and right drive wheels, and an oscillation mechanism that causes the front vehicle body and the rear vehicle body to oscillate relative to each other. The oscillation-type vehicle being capable of carrying out drive control of the left and right drive wheels such that the drive wheels behave differently from each other in response to oscillation of the oscillation-type vehicle, wherein the drive control of the left and right drive wheels is carried out using information on the oscillation and information on a speed of vehicle.

The disclosure provides a control device capable of smoothly performing a turning operation due to an external force for a mobile body having a movement operation part and a seat part of occupant. A control device which performs a movement control of movement operation parts a mobile body estimates a movement rotational force in the yaw direction according to a movement of the mobile body and a rotational driving force in the yaw direction according to a driving forces of an actuator, and estimates an external force rotational force, which is a rotational force in the yaw direction due to an external force applied to the mobile body, based on these estimation values. A turning operation of the mobile body is performed according to an estimation value of the external force rotational force and a maneuver operation of the mobile body.

In an example, a torque vectoring unit includes an inner rotor, an outer rotor enclosing the inner rotor, and a stator enclosing the outer rotor, with the inner rotor, the outer rotor and the stator being concentrically arranged to one another. The inner rotor is drivingly connectable to a first wheel and the outer rotor is drivingly connectable to a second wheel, and the inner rotor and the outer rotor represent a first electric motor and the outer rotor and the stator represent a second electric motor.

A vehicle includes a first axle have a first electric machine, a second axle having a second electric machine and a controller. The controller is programmed to, in a user-selected four-wheel drive mode, command a first torque to the first electric machine based on a driver-demanded torque and a speed of the second axle, and command a second torque to the second electric machine based on a comparison of the driver-demanded torque and the first torque and further based on a speed of the first axle.

A comprises a vehicle control unit, VCU, and a control module, CM, configured to control the torque actuators. The VCU is configured to send to the CM a parameter request and a desired recuperation power or a desired parameter split ratio. If the CM determines that these are conflicting targets, then based on one or more predefined criteria, the CM will apply a parameter value and allocate a recuperation power or a parameter split ratio such that the applied parameter value is different from the requested one and/or the allocated recuperation power or parameter split ratio is different from the desired one. A method of controlling a wheel is also disclosed.

The invention relates to a control system for controlling a torque generator of a vehicle. The control system is configured to receive one or more electrical signals indicative of a surface indicator; receive one or more electrical signals indicative of a deceleration demand; select a surface type from a plurality of predetermined surface types based on said one or more electrical signals indicative of a surface indicator; determine a target vehicle deceleration in dependence on the selected surface type; determine, based on said one or more electrical signals indicative of a deceleration demand, a requirement to decelerate the vehicle; and in dependence on determining said requirement, output a control signal to the torque generator. The control signal is configured to cause the torque generator to provide the target vehicle deceleration.

A direct current traction motor control system includes plural motors of with each of the motors configured to be coupled with a different axle of a vehicle and to rotate the axle to propel the vehicle. The motors are coupled with a DC bus and configured to receive DC via the DC bus to power the motors. The system also includes plural switch assemblies with each of the switch assemblies having an H-bridge circuit coupled with a different motor of the motors to control rotation of the motor. The system includes a controller configured to communicate control signals to the switch assemblies to individually control the H-bridge circuits to control one or more of torques output by the motors or rotation directions of the motors.

Controlling a maximum vehicle speed for an industrial vehicle includes determining, by a processor of the industrial vehicle, a torque applied to the traction wheel of the industrial vehicle; converting the torque to an equivalent force value; and determining an acceleration of the industrial vehicle while the torque is applied to the traction wheel. Additional steps include calculating a load being moved by the industrial vehicle, based at least in part on the acceleration and the equivalent force value; and controlling the maximum speed of the industrial vehicle based on the calculated load being moved by the industrial vehicle.

An operating device of an electric vehicle enables an electric vehicle to be operated, the electric vehicle having: left and right driving wheels; and left and right driving motors respectively independently driving these left and right driving wheels. The operating device has: a joystick operable to move so as to issue a turning direction instruction of the vehicle; and a traveling instruction portion issuing a traveling instruction of the vehicle by operation different from movement operation of this joystick. The joystick has a grip operable to be gripped by an occupant of the vehicle. By making a difference between rotating speeds of the left and right driving motors based on a combination of the turning direction instruction of the joystick and the traveling instruction of the traveling instruction portion, a gentle turn or a pivotal brake turn of the vehicle is performed.

Embodiments of the invention are directed toward a geared traction drive system configured to drive a wheel of a vehicle, comprising: a driveshaft for transmitting power to the wheel; an electric drive motor for driving the driveshaft, the electric drive motor configured to receive signals from a vehicle dynamic control system to command a required speed; a gear reduction component for reducing the speed of the motor by a predetermined factor to a lower speed suitable for driving the wheel; and a drive electronics component that works with the electric drive motor to drive the wheel to the speed commanded by the vehicle dynamic control system.
