  • Patent number: 7813859
    Abstract: When a vehicle stops, a brake control unit maintains a braking force applied on a wheel by a braking-force application unit for maintaining a halted state. In this state, if a driver depresses the accelerator pedal to execute starting of the vehicle, the braking force is gradually decreased, and the vehicle starts at a speed that accords with a degree of accelerator opening and a gradient of a road on which the vehicle is stopped. When a movement direction at this time is the same as a movement direction intended by the driver, the braking force is decreased to zero for smooth starting. When the movement direction is opposite to the intended movement direction, the braking force is increased to control the movement in the opposite direction, such that the movement changes from the opposite direction to the same direction, and finally, smooth starting in the desired direction is executed.

  • Patent number: 6886426
    Abstract: In a shift lever apparatus, a shift position can be changed from a “P” shift position only by turning a shift lever to a right side of a vehicle. Unless a brake is operated, it is possible to maintain a state in which a stopper portion is disposed in a right side of the vehicle in an abutting portion. Therefore, the abutting portion abuts the stopper portion, and the shift lever cannot be turned to the right side of the vehicle. When the brake is operated, a rotary plate is rotated in accordance that the shift lever turns to the right side of the vehicle. Accordingly, the abutting portion does not abut the stopper portion, and the shift lever can be turned to the right side of the vehicle.

  • Patent number: 6689014
    Abstract: This invention is an improved park position locking system for controlling the conditions for removing an automatic transmission gearshift 90 from a PARK position. An electronic system controller 30 and the transmission controller 16 are engaged to a common data bus 18. Vehicle control system 10 comprises the electronic system controller (ESC) 30, which is the primary component of a vehicle electronic control system. ESC 30 manages and communicates with a number of vocational controllers disposed on a vehicle 13 and executes a load management program which oversees the total load imposed on the vehicle electrical system and power train by various accessories installed on the vehicle 13. Such communication is by a standard communication protocol that may be the SAE J1939 protocol over the common data bus 18. The ESC 30 is programmed to ensure that an operator of the vehicle may not move the gearshift 90 out of a PARK position without first depressing a service brake pedal.

  • Patent number: 6676564
    Abstract: A brake-shift interlock unit includes a pair of coils which are disposed in a coaxial relationship. A plunger is movable in a passage which extends through the coils. Upon actuation of a vehicle ignition switch, while a brake switch remains in an unactuated condition, a plunger pull coil is energized to move the plunger from the extended position to the partially retracted position. At this time, the plunger engages a stop member. Upon actuation of the vehicle brake, a stopper hold coil is de-energized to enable a shift lever to move.

  • Publication number: 20030087725
    Abstract: In a shift lever apparatus, a shift position can be changed from a “P” shift position only by turning a shift lever to a right side of a vehicle. Unless a brake is operated, it is possible to maintain a state in which a stopper portion is disposed in a right side of the vehicle in an abutting portion. Therefore, the abutting portion abuts the stopper portion, and the shift lever cannot be turned to the right side of the vehicle. When the brake is operated, a rotary plate is rotated in accordance that the shift lever turns to the right side of the vehicle. Accordingly, the abutting portion does not abut the stopper portion, and the shift lever can be turned to the right side of the vehicle.
