CONTROL APPARATUS FOR VEHICLE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18320286 titled 'CONTROL APPARATUS FOR VEHICLE
Simplified Explanation
- The patent application describes a control apparatus for a vehicle that has an electric motor and a parking lock mechanism. - The parking lock mechanism includes a parking gear, a lock tooth, and an actuator for moving the lock tooth. - When the shift operation position is switched to the 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 while the vehicle is stopped, the electric motor outputs a torque in the opposite direction of rotation of the drive wheels due to a gradient of the road surface. - The outputted torque is increased until rotation of the electric motor is detected. - The purpose of this innovation is to prevent the vehicle from rolling on a gradient when parked by utilizing the electric motor's torque in the opposite direction of rotation.
Original Abstract Submitted
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.
