A vehicle remote control apparatus has: A) a first transmitter for outputting an authentication request signal to a mobile device including a radio terminal assigned with an identification code special to a vehicle and outputting an authentication response signal corresponding to the identification code; B) a second transmitter for outputting an interference wave to cancel the authentication request signal at the same time as the first transmitter transmits the authentication request signal; C) a receiver for receiving the authentication response signal output from the mobile device in response to the authentication request signal, thereby checking authenticity of the authentication response signal; and D) a controller for controlling operation of an on-vehicle equipment based on the result of authentication of the authentication response signal.

A combination switch enabling the distance over which a signal can be received to be increased and the limitation on the direction to be reduced in a keyless entry system for automobiles. The combination switch has a main body (1) including a light control switch unit (2), a wiper control switch unit (3), and receiving means for receiving a signal from a transmitter main body (12) of a keyless entry system. Thus, a combination switch for automobiles incorporated in a keyless entry system and having a wide reception range.

The present invention aims at providing a rotation angle detector capable of detecting and storing information for a direction and an angle of rotation of steering wheel while maintaining a condition of reduced power consumption from a battery, when an engine is not running. In achieving the object, the invention discloses a structure, wherein the detector keeps a control means (8) including a memory unit (11) in a memory back-up mode when an ignition switch (7a), i.e. a main switch, is turned off, switches a power supply for sensor elements (3a), (3b) and (4) into a mode of low consumption of current, which is smaller than that of the normal current by a control signal of the control means (8), and allows the control means (8) to activate the sensor elements (3a), (3b) and (4) operative in the normal mode after a confirmation of an output signal from at least one of the sensor elements (3a) and (3b) when the steering wheel is moved, and thereby the detector is capable of detecting the direction and the angle of rotation out of the information for rotation of the steering wheel.

The rotation-angle detecting device of the present invention contains two rotators having the same number of teeth, which engage with a gear fixed to a rotation-detecting axle as a detected object. The detecting device further includes a controller. Receiving a rotation-angle signal from the rotators, the controller amplifies the signal, performs calculations, and stores the results. The controller converts each rotation-angle signal from each rotator into each periodic waveform output having the same crest value, and stores an initial phase difference value at initial setting. In driving operations, monitoring an evaluation value calculated with reference to the initial phase difference value, the controller determines that abnormalities occurred, if the evaluation value exceeds a predetermined abnormality-evaluation threshold.

The automobile of the present invention is provided with a capacitor for backup use in case of disconnection or breakdown of a battery. When a start switch is turned off, the collected charge in the capacitor is supplied to a device in which a large current is flowing, such as discharging resistor, motor or lamp, or a device in which a small current is flowing, such as dark current consuming device, and therefore, after the start switch is turned off, power consumption of the battery can be suppressed.
