Abstract

It is possible to, by checking a timer function in advance, make diagnosis on the power supply function by means of an alarm signal output by a clock IC before a driver leaves a driver'"'"'s seat to induce the driver to repair and to switch over to a way where the relevant function is not used.

An electric vehicle control device, which has at least a start signal for a vehicle and an alarm signal by a clock as means for initiating power supply, checks an output of the alarm signal by the clock after start-up by the power supply, holds the output of the alarm signal until start signals other than the alarm are all turned off, and notifies of the power supply being continued by way of the alarm signal whose output is held after the start signals other than the alarm are turned off.

Claims

1. An electric vehicle control device having at least a start signal for a vehicle and an alarm signal by a clock as means for initiating power supply, comprising:

first means that checks an output of the alarm signal by the clock after start-up by the power supply;

second means that holds the output of the alarm signal until start signals other than the alarm are all turned off; and

third means that notifies of the power supply being continued by way of the alarm signal whose output is held after the start signals other than the alarm are turned off.

2. The electric vehicle control device according to claim 1, comprising:

monitor means including at least

means that monitors a notification signal notifying of the power supply being continued,

means that issues a warning by means of display or sound if there is no notification signal, and

second power supply means different from the power supply means.

3. The electric vehicle control device according to claim 2, comprising:

means that prohibits devices from stopping if the monitor means issues a warning, the stopping being caused by the start signals other than the alarm being all turned off.
