An apparatus and a method for controlling pitch reduction may include a sensor device that measures a wheel speed and a longitudinal acceleration of a vehicle, a pitch rate estimation device that performs pseudo-integral of a difference between a wheel acceleration determined from the wheel speed and the longitudinal acceleration to determine an estimation value of a pitch rate, and a pitch motion reduction controller that generates a control command for implementing a motor torque in which the determined estimation value of the pitch rate is reflected and transmits the control command to an electric motor of the vehicle.

Provided is an electric vehicle control method. The electric vehicle control method includes: a disturbance torque estimation process of calculating a disturbance torque estimation value including an influence of a road surface gradient; a speed parameter acquisition process of acquiring a speed parameter relating to a vehicle speed; a stop process of calculating a stopping basis torque target value so as to converge a torque command value to the disturbance torque estimation value in accordance with a decrease of a speed parameter; and a vibration damping process of calculating a stopping correction torque target value by performing filterring on the stopping basis torque target value. In the vibration damping process, the torque command value is set based on the stopping basis torque target value in a first just-before-stop period set in a relatively high vehicle speed range, and is set based on the stopping correction torque target value in a second just-before-stop period set in a relatively low vehicle speed range.

A small electric vehicle includes: a vehicle body that has a forward and backward direction, and a width direction; left and right driving wheels provided apart in the width direction of the vehicle body; left and right motors connected so as to respectively transmit power to the left and right driving wheels; an operation unit that includes a joystick-type operation piece; and a control unit for controlling the left and right motors according to an amount of operation on the operation piece, wherein the control unit is configured to execute deceleration and stop control when the operation piece is returned to the neutral position during travel, and execute rapid stop control irrespective of an amount of operation in left and right directions when the operation piece is tilted backward during forward travel at a speed equal to or greater than a predetermined threshold.

A one pedal driving system for an electric vehicle including one or more electric motors includes a controller in wireless communication with one or more external vehicle networks. The controller executes instructions to receive, from the one or more external vehicle networks, an active zone notification that indicates the electric vehicle is traveling into a one pedal driving zone. The one pedal driving zone represents a section of roadway where the electric vehicle decelerates from an initial speed. The controller executes instructions to receive a pedal notification that a driver foot is removed from an accelerator pedal of the electric vehicle. In response to receiving the active zone notification and the pedal notification, the controller instructs the electric vehicle to decelerate from the initial speed by a regenerative braking torque that is created by the one or more electric motors to counteract a forward momentum of the electric vehicle.

A control apparatus for a vehicle that includes an electric motor and a parking lock mechanism for stopping rotation in a power transmission path between the electric motor and drive wheels. The parking lock mechanism includes: a parking gear, a lock tooth that is to mesh with the parking gear and an actuator for moving the lock tooth. When a shift operation position is switched to a parking position, the lock tooth is moved by the actuator to mesh with the parking gear. When the shift operation position is switched from the parking position to another position in a state in which the vehicle is stopped, the electric motor outputs a torque acting in a rotational direction opposite to a direction of rotation of the drive wheels due to a gradient of a road surface, and the outputted torque is increased until rotation of the electric motor is detected.

A parking brake fail safety control system and method for a vehicle having an electric-axle, may enable safe parking braking on a level ground, a slope, etc. By controlling the torque from a first motor configured for a rear wheel-first electric-axle and the torque from a second motor configured for a rear wheel-second electric-axle to have the same magnitude in opposite directions and by increasing/decreasing the torque from the first motor and the torque from the second motor, depending on a change of wheel speed when a parking brake fails.

The electric walking assisting vehicle includes a vehicle body; left and right driving wheels; left and right motors operable to individually transmit power to the left and right driving wheels; gripping parts provided in an upper portion of the vehicle body and can be gripped by a user in a standing and walking posture; an electromagnetic brake for locking the left and right driving wheels or the left and right motors; a forcible release for the electromagnetic brake; an inclination sensor detecting an inclination of the vehicle body; and a control unit controlling the left and right motors, and during stopping of the left and right motors, when the inclination detected by the inclination sensor is less than a predetermined threshold value, the forcible releasing means for the electromagnetic brake is enabled and when the inclination is the predetermined threshold value or more, the forcible releasing means is disabled.

A drive force control system controls acceleration of a vehicle accurately in line with an operation of an accelerator pedal to improve an acceleration feel. A controller calculates a corrected target acceleration when a required acceleration is large and an operating speed of the accelerator pedal is fast, and converts the corrected target acceleration into a target driving force to propel the vehicle so as to achieve the corrected target acceleration by generating the target driving force.

Methods and systems for operating axles of a vehicle are provided. In one example, relationships between accelerator pedal position and driver demand torque may be adjusted as a function of a vehicle's geographical location. Further, a relationship between brake pedal position and requested braking amount may be adjusted as a function of a vehicle's geographical location.
