    Abstract: A motor performing power driving and regeneration has an inverter, a mechanical brake, a power storage device supplying energy to the motor, an accelerator operator controlling the motor to adjust a drive torque of a driving wheel, a mechanical brake operator controlling the mechanical brake to adjust a braking torque, a regenerative brake operator adjusting a braking torque of the driving wheel and recovering the energy into the power storage device, and a detector detecting a rotation speed of the motor. When the rotation speed of the motor is equal to or higher than a predetermined value, a predetermined braking torque, based on an operation amount of the regenerative brake operator, is generated by regenerative braking.

    Abstract: The invention relates to a method for operating a vehicle (1), wherein the vehicle (1) comprises: a driveline (2, 4) configured to provide a driving power to at least one wheel (3) of the vehicle (1) for propulsion of the vehicle (1); and a wheel brake system (5) configured to brake the vehicle (1), wherein the method comprises the steps of: receiving (S1) a control signal indicative of a request for acceleration or deceleration of the vehicle (1), wherein the acceleration or deceleration control signal is generated by an accelerator device, such as an accelerator pedal, configured to be acted upon by a driver of the vehicle (1); and controlling (S2) the driveline (2, 4) in response to the acceleration or deceleration control signal. The method comprises the steps of: providing (S3) an acceleration or deceleration threshold limit representing i) the highest vehicle acceleration that can be allowed for the received acceleration control signal in the current circumstances, or ii) the lowest vehicle deceleration that can be allowed for the received deceleration control signal in the current circumstances; determining (S4) a resulting vehicle acceleration or deceleration that is or will be the result from the step of controlling the electric driveline in response to the acceleration or deceleration control signal; comparing (S5) the resulting vehicle acceleration or deceleration with the corresponding acceleration or deceleration threshold limit and determining whether the resulting vehicle acceleration is or will be higher than the acceleration threshold limit or whether the resulting vehicle deceleration is or will be lower than the deceleration threshold limit; and when the resulting vehicle acceleration is or will be higher than the acceleration threshold limit or when the resulting vehicle deceleration is or will be lower than the deceleration threshold limit; applying (S6) the wheel brake system (5) so as to reduce an actual vehicle acceleration or increase an actual vehicle deceleration towards the corresponding acceleration or deceleration threshold limit.

    Abstract: The general layout for a three wheel drive, three wheel vehicle with two steerable driven wheels in the front of the vehicle, utilizing one or two motors to drive the front wheels, and a rear motor to drive the rear wheel. The vehicle maximizes performance of a three wheel vehicle by controlling torque on all three wheels. This is used to manage vehicle lateral dynamics while maximizing wheel traction for acceleration. Utilizing compact motors, in-hub motors, or direct connect motors allows a significant portion of the vehicle's weight to be moved forward, while integrating the location of the passenger seating, steering, and driven wheels results in a highly stable three wheel vehicle. The layout maintains the traditional bucket or bench style seats as found in today's automobiles, and yet allows for weighting and cockpit adaptability for different market demographics.

    Abstract: A vehicle includes a drive motor with electrically upstream electric converter, a drive controller generating converter control signals actuating the converter for driving and normal braking operation, and an immobilizer electrically connected between the converter and the drive controller preventing converter control signals which would produce a driving operation of the drive motor from being forwarded to the converter when the vehicle is stopped, in particular at a stop. An alternate regulating device and a monitoring device allow activation of a special braking mode in the presence of an emergency braking command and in the event of which the drive controller is deactivated or at least signal flows of converter control signals of the drive controller to the immobilizer are interrupted, the immobilizer is activated, and converter control signals producing braking operation of the drive motor are transmitted to the converter through the immobilizer by the alternate regulating device.

    Abstract: A vehicle driving system that can suppress a difference in effect of vehicle attitude control between the cases where a friction braking force is applied and not applied, is provided. The system includes a rotating electric machine, a battery, a steering apparatus, a steering angle sensor, a brake actuator that applies a friction braking force, a friction braking force sensor, and a controller that sets a deceleration torque based on a steering speed detected by the steering angle sensor and controls the rotating electric machine to apply the deceleration torque to a front wheel of the vehicle, thereby executing a vehicle attitude control. When the friction braking force is applied to the wheels by the brake actuator during the vehicle attitude control, if the friction braking force is large, the controller corrects the deceleration torque to a larger value than when the friction braking force is small.
