Abstract

PURPOSE:To prevent useless consumption of a power by a method wherein, in a device which turns ON a main source through radio communication between a portable key and the vehicle side, when radio communication is not effected in a normal state when the main source is in an ON-state and an engine is brought into a stop state, the main source is turned OFF. CONSTITUTION:In a motor bicycle, when a main source 9 is in an ON-state and the stop time of an engine exceeds a given time, a request signal of a given frequency is transmitted from a transmitting receiving unit 6 on the vehicle side for a given period. When the request signal is received by a transmitter receiver 7 carried by a user, a memory code signal intrinsic to the user is transmitted from the transmitter receiver 7 the given number of times. The memory code signal is received by the transmitting receiving unit 6, and compared and collated with a set code, and when the two codes coincide with each other, the main source 9 is held in state that it is left in an ON-state. Meanwhile, when the user is parted far away from a vehicle at a current time and the memory code is not received, the main source 9 is automatically turned OFF.

The parking lamp 29 can be turned on only when the main power source 9 is turned off, and is turned off when the main power source a9 is turned on.

Next, the operation of the vehicle power control device according to the present invention will be explained with reference to FIGS. 3 to 5.

First, press the on switch 3a on the main board 3 (
In response to this, the transmitter/receiver unit 6 provided in the vehicle 1 transmits a request signal of a predetermined frequency for a predetermined period (S2). When the card-shaped transceiver 7 carried by the user receives this request signal (33), the transceiver 7 automatically transmits a user-specific PIN code signal a predetermined number of times (34). When the transmitting/receiving unit 6 receives the code (S5), it compares and verifies it with a preset setting code (S6).

If the password code signal and the setting code match, the main relay 24 is energized and the main power source 9 is turned on (S7). Note that if radio wave communication is not possible due to a dead battery in the transceiver 7 or a malfunction in the transceiver unit 6, the emergency switch 26 can be turned on by operating the mechanical key 27 housed in the transceiver 7 (S8 ), you can also turn on the main power supply 9 (S

is turned off, and the main power supply 9 is also turned off (321).

Next, depending on whether or not the handle 2 needs to be locked (322), if the handle 2 is to be locked, the handle 2 is rotated to the locked position and then the operating rod 14 provided on the handle lock actuator 10 is pulled. By (S2
3) The lock pin 12 protrudes outward from the case II, and the plunger 16 engages with the retaining groove 18 of the lock pin 12 by the biasing force of the spring 17, thereby locking the handle 2 (324).

Next, it is determined whether or not the parking lamp 29 needs to be lit (S2
5), when turning on the parking lamp 29, press the parking indicator 3C on the main board 3 (S26). A request signal is transmitted for a predetermined period of time (327). When the transmitter/receiver 7 carried by the user receives this request signal (32
B) The transceiver 7 transmits a user-specific password code signal a predetermined number of times (329). Next, the transmitting/receiving unit 6 receives this PIN code signal (530) and compares and verifies it with the setting code (S31). If the PIN code signal and the setting code match, the park relay 28 is activated. The parking lamp 29 is turned on (332).

Further, when the main power source 9 is in the on state, it is determined whether the engine is in a rotating state or a stopped state (S33), and according to the determination of the engine stop time (S34), the engine is in a stopped state for one minute or more. If there is a request signal of a predetermined frequency from the transmitting/receiving unit 6,
When the transceiver 7 carried by the user receives this request signal (335), which is repeatedly transmitted every minute (836), the transceiver 7 transmits a user-specific password code signal a predetermined number of times (337). Next, the transmitting/receiving unit 6 receives this password code signal (538) and compares and verifies it with the setting code (S39).

Then, when the PIN code signal and the setting code match, the main power supply a9 is held in the on state (54
0). On the other hand, if the transmitting/receiving unit 6 does not receive the PIN code signal from the transmitting/receiving device 7 even though the request signal is transmitted from the transmitting/receiving unit 6 (when the user is away from the vehicle), the main power source 9 It is automatically turned off (S41).

(Effects of the Invention) As described above, in the present invention, when the main power source is on and the engine is stopped, wireless communication is repeatedly performed between the mobile key and the vehicle at regular intervals, and the wireless If communication does not occur normally for a specified period of time, the main power supply will be turned off, so if the kill switch is used to stop the engine or the engine stalls, the main power supply will be turned off. Even if you leave the vehicle without stopping, the main power supply automatically turns off, which has the excellent effect of not wasting power.
