Abstract: This control device for a vehicle switches a shift range of an automatic transmission through the use of an actuator, wherein the control device for a vehicle is characterized in being provided with a shift selection unit for receiving a shift position selection from a driver and a control unit for switching the shift range to a parking range through the use of an actuator when a vehicle power source turns off or when a drive power source stops, the control unit maintaining a neutral range, when the vehicle power source turns off or when the drive power source stops, until the elapse of a first prescribed time after the shift selection unit receives a neutral position selection while the vehicle power source is on or while the drive power source is driving.

Abstract: A system for maintaining a vehicle including a shift-by-wire transmission in a neutral-hold mode is provided. The system includes a transmission control unit in signal communication with the shift-by-wire transmission and an internal control unit of the vehicle. The transmission control unit is configured to control a gear configuration of the shift-by-wire transmission. An external control unit is in signal communication with the transmission control unit. The external control unit is configured to transmit a neutral-hold mold activation signal.

Abstract: In a shift by wire transmission, a control unit limits the shift position (P, R, N, D, L) to be changed beyond a prescribed shift position depending on an initial shift position and an amount of the movement of the shift member in a single shifting operation. Thereby, even when the shift member is excessively advanced or otherwise improperly advanced, the actually selected shift position can be suitably selected so that an undesired change of the shift position can be avoided. The control unit may also limit the selected shift position to be changed beyond a prescribed shift position depending on a traveling speed of the vehicle so that an improper change in the shift position due to vehicle speed constraints can be avoided by using a simple structure.

Abstract: A revolution-speed/temperature hybrid sensor includes a hybrid sensor unit which has a five-input-three-output convertor and outputs a revolution-speed/temperature hybrid signal, and a revolution-speed/temperature detector for separating the revolution-speed/temperature hybrid signal. The five-input-three-output convertor has an adder for adding the revolution speed signal of pulse waveform and temperature signal of analog form so as to generate a revolution-speed/temperature hybrid signal. By virtue of the five-input-three-output convertor, the revolution-speed/temperature hybrid sensor requires a smaller number of harnesses and is downsized compared to a conventional arrangement.

Abstract: Pulse signal generating device includes a duty cycle calculator for calculating a target duty cycle at predetermined intervals, a duty cycle comparator for making a comparison between the target duty cycle calculated by the duty cycle calculator and a current duty cycle of a pulse signal being currently output from the device, and a pulse signal adjuster. The duty cycle comparator determines whether the target duty cycle has presented a variation (increase or decrease) from the current duty cycle by over a predetermined value. Once the duty cycle comparator detects that a difference between the target duty cycle and the current duty cycle is more than the predetermined value, the pulse signal adjuster adjusts the pulse signal, using a pulse rise point immediately before the detection as an adjustment reference point, in such a manner that the pulse signal assumes a duty cycle corresponding to the target duty cycle.
