Abstract: A vehicular shift control apparatus for a vehicle provided with a parking lock device selectively switched to a locking position in which rotation of wheels of the vehicle is prevented and a non-locking position in which the rotation of the wheels is not prevented, by an operation of an electrically operated actuator, the vehicular shift control apparatus being configured to perform a failure diagnosis to determine whether the actuator is operable or not, the vehicular shift control apparatus includes: the vehicular shift control apparatus permits the operation of the actuator if a supply voltage to the actuator is raised from a value lower than a predetermined threshold supply voltage value to a value not lower than the threshold supply voltage value after a determination that the actuator is inoperable is obtained in the failure diagnosis.

Abstract: A control system for a work vehicle includes: a negative-type parking brake device that starts operating in response to a parking brake instruction; an output device that outputs the parking brake instruction; a service brake device that operates in response to an operation of a brake pedal by an operator; and a brake control device that operates the service brake device regardless of a pedal operation by the operator when the parking brake instruction is output from the output device.

Abstract: In a device for securing the standstill of a motor vehicle with a distance-related longitudinal dynamic control module, which is contained in at least one electronic control unit and by which the motor vehicle is decelerated down to a standstill while maintaining a defined distance from a target object, at least until reaching the standstill, a nominal brake torque is defined by the longitudinal dynamic control module for a brake control module. At a defined first time after a detected standstill of the motor vehicle, the longitudinal dynamic control module transmits a transfer signal to the brake control module. Thereupon, independently of the predefinition of a nominal brake torque by the longitudinal dynamic control module, the brake control module alone builds up and/or holds a wheel brake torque in the sense of a parking brake function.

Abstract: A drive control system for an electric vehicle and a method of drive control of the electric vehicle. The drive control system for the electric vehicle includes a drive motor target torque calculation processing device for calculating a drive motor target torque representing a target torque of a drive motor; and a drive motor target torque restriction processing device that judges whether or not a parking mechanism is in operation and, if the parking mechanism is in operation, restricts variations in the drive motor target torque.

Abstract: A geared motor in which user needs for change gear ratios are met with flexibility and reliability, and an increase in noise is suppressed. The geared motor comprises a motor unit and a change gear unit for transmitting rotational power from this motor unit in combination. A simple planetary roller unit including a simple planetary roller mechanism and a casing for accommodating this simple planetary roller mechanism is interposed between the change gear unit and the motor unit. The simple planetary roller mechanism has a sun roller, planetary rollers, and a ring roller. Flange portions spreading outward in the radial directions of the sun roller are formed on both axial ends of the casing. One of the flange portions is coupled to the motor unit, and the other is to the change gear unit. Moreover, the geared motor is configured so that rotational power from the motor unit is transmitted to the change gear unit through the simple planetary roller unit.

Abstract: The actuator uses an electric motor to drive a recirculating ball screw thread connection, to hold a brake-actuation spring at bay. After the spring has been compressed to the brakes-off position, the electric motor is de-energized. Then, the screw-thread connection is prevented from rotating and backing off, by virtue of the fact that the electric motor is connected to the screw thread via a high-reduction worm gear-box, which will not reverse-drive. An electric clutch is included between the screw-thread connection and the gear-box, the clutch being held, electrically, in the locked or drive condition while the brake is required to be held off. The brake is applied by releasing or de-energizing the clutch to the non-drive or free condition.
