A drive system operation apparatus that is easy to operate and improves the level of security in a vehicle. A gearshift operator and an engine switch are located near each other. A cover covers the gearshift operator and the engine switch. The cover is opened when predetermined conditions, including establishment of wireless communication with an authorized key, are satisfied.

Vehicle drive system operation apparatus and vehicle drive control system

A relative rotational angle of a rotary body is measured with respect to a reference angle. First openings are arranged about the circumference of a disk, which rotates integrally with the rotary body, at predetermined pitches. A first detecting element detects the first openings and generates a first binary code. The relative rotational angle of the rotary body is computed in accordance with the first binary code. A second detecting element detects the second openings and generates a second binary code. The reference angle of the rotary body is computed and reset in accordance with the second binary code. Third openings are concentrical with the first and second openings. A third detecting element detects the third openings and generates a third binary code. The reference angle is determined based on the combination of the first and third binary codes.

Apparatus for detecting rotational angle

A control device for controlling an antiglare mirror in vehicles. The inner mirror, which has a gel-type EC cell, reduces its mirror reflectivity as the positive voltage applied thereto increases. A rear light sensor receives the light from behind through the inner mirror. A comparison decision circuit detects the intensity of the light from behind in accordance with the light receiving state of the rear light sensor and an ambient light sensor. A driving circuit applies a positive voltage to the EC cell of the inner mirror so that the light from behind has a predetermined intensity level. A control circuit supplies a negative or positive voltage to outer mirrors in accordance with the positive voltage applied to the inner mirror. The outer mirrors enhances their mirror reflectivity as the negative voltage level applied becomes high and reduces their mirror reflectivity as the positive voltage level applied becomes high.
