A system for deterring theft of a vehicle having a plurality of opening and closing parts (doors, hood, trunk lid, etc.) divided into a first group of opening and closing parts (singular or plural) and a second group of opening and closing parts (singular or plural) includes an alarm device for outputting an alarm exteriorly of the vehicle, an open/closed state sensor for sensing individual open and closed states of each of the plurality of opening and closing parts and outputting signals indicative of the states sensed, a device for sensing that an ignition signal for starting the vehicle engine has been generated, a first setting device for setting the vehicle to a first armed phase in response to driver operation, a first actuating device for actuating the alarm in the first armed phase in response to at least one signal from among the ignition signal and signals indicative of the open states of the plurality of opening and closing parts, a second setting device for setting the vehicle from the first armed phase to a second armed phase in response to driver operation, and a second actuating device for actuating the alarm in the second armed phase in response to at least one signal from among the ignition signal and signals indicative of the open states of the plurality of opening and closing parts belonging solely to the second group. Thus, theft is deterred not only in the first armed phase but also in the second armed phase.

Theft deterrent system

A switch assembly in which a lever rotates a separate rotary member to operate a first electrical switch and the lever pivots within the rotary member to operate a second electrical switch. The rotating member is held at a first position and a second position when the rotary member is turned. A solenoid is linked to a cam that restores the lever to a neutral position between the first and second positions. A return mechanism returns the pivoting member to its original position when the lever is released.

Switch assembly

There is provided a dimmer passing device for a headlamp of a vehicle having a light switch which drives a light relay when it is on, a momentary control switch which activates the light relay when it is on, a latch circuit which alternately turns on and off an internal switching element in response to the on state of the momentary control switch, and a dimmer relay which causes the light relay to energize a low beam of the headlamp when the internal switching element is turned off and which causes the light relay to energize a high beam of the headlamp when the internal switching element is turned on.

Dimmer passing device for headlamp of vehicle

A vehicle automatic transmission including a torque converter, a multiple stage transmission gear mechanism connected with the torque converter and a hydraulic control circuit for automatically selecting one of gear stages of the transmission gear mechanism. The hydraulic control circuit includes a kickdown control device which functions to shift down the gear mechanism when the engine control foot pedal is substantially fully depressed. Depending on the vehicle running condition, the kickdown control device shifts down the gear mechanism by two gear stages. The hydraulic circuit includes control circuit which functions to shift down the gear mechanism at first by one gear stage and then by a further one stage in sequence when a two stage shift down is required.

Depending on the vehicle running condition, the kickdown control device shifts down the gear mechanism by two gear stages. The hydraulic circuit includes control circuit which functions to shift down the gear mechanism at first by one gear stage and then by a further one stage after a certain time delay when a two stage shift down is required.
