  Furthermore, the vehicle load output control device 2 is provided with an execution condition for determining whether or not to operate the load, and is provided with the initial state detecting means 26 capable of detecting whether or not the vehicle is in an initial state, and satisfies the execution condition. Even if not, it has a function of operating the load when the initial condition is satisfied.

  More specifically, whether or not to activate the load comprising the rear defogger 4 and the deaiser 6 depends on the execution conditions of the rear defogger output control in the rear defogger function and the suspension of the rear defogger output in the rear defogger function, and the deaiser in the deaiser function. Judgment is made according to the execution condition of the deaiser output stop in the output control and deaiser function.

  Even when the execution condition is not satisfied, when the initial condition is satisfied, the load is operated by the vehicle load output control device 2, that is, the rear defogger output and the deaiser output are executed, and 15 minutes have passed since the output started. In this case, the rear defogger output is canceled and the deaiser output is canceled.

  Reference numeral 66 is an alarm buzzer means provided in the vehicle load output control device 2, and 68 is a keyless means provided in the vehicle load output control device 2.

  For reference, the alarm buzzer means has a function to notify the buzzer of forgetting to remove the key, forgetting to turn off the light, or when the vehicle is reversing, and the keyless means is a door by a keyless transmitter (not shown). It has a function to lock and release.

  When the control program of the vehicle load output control device 2 is started (100), the shipment mode, that is, the shipment mode in which the charge switch 28 is turned off from the battery connection of the vehicle load output control device 2 is detected and initialized. A determination is made as to whether or not a state is present (102).

  When the determination (102) is YES, the process proceeds to determination (104) of whether the off state of the charge switch 28 has elapsed for 15 seconds from the battery connection, and when the determination (102) is NO. Then, the process proceeds to the determination (106) of whether or not the execution condition of the rear defogger output control in the rear defogger function is satisfied.

  If the determination (104) is NO, the process proceeds to determination (108) as to whether or not the rear defogger switch 34 is ON. If the determination (104) is YES, the shipping mode is canceled (110 Then, the process proceeds to determination (106) of whether or not the execution condition of the rear defogger output control in the rear defogger function is satisfied.

  Further, in the determination (108) of whether or not the rear defogger switch 34 is on, if the determination (108) is NO, whether or not 15 seconds have passed since the battery switch was connected and the charge switch 28 has been turned off. Returning to the determination (104), if the determination (108) is YES, the rear defogger output is turned on (112), and after this output starts, the process proceeds to the determination (114) as to whether or not the output time has exceeded 15 minutes. To do.

  If the determination (114) is NO, the process returns to the determination (104) of whether or not the off state of the charge switch 28 has elapsed for 15 seconds from the battery connection. If the determination (114) is YES, After the rear defogger output is turned off (116), the process returns to the determination (104) of whether or not the off state of the charge switch 28 has elapsed for 15 seconds from the battery connection.

  Further, in the determination (106) of whether or not the execution conditions of the rear defogger output control in the rear defogger function described above are satisfied, if this determination (106) is NO, it is determined whether or not it is the shipping mode ( Returning to 102), if the determination (106) is YES, the rear defogger output is turned on (118), and after this output starts, the process proceeds to determination (120) as to whether or not the output time has exceeded 15 minutes. .

  If the determination (120) is NO, the process returns to the process (118) for turning on the rear defogger output. If the determination (120) is YES, the rear defogger output is turned off (122).

  Therefore, the shipment mode is automatically canceled after the vehicle shipment inspection and before reaching the user.

  Thus, the vehicle load output control device provided with a function of energizing the load for operating the load function for a preset time when it is detected by the initial state detecting means 26 as the initial state. 2, the control mode in which the load is operated unconditionally at the time of shipping inspection at the factory is limited only for a preset time, for example, from when the battery is connected to when the charge switch 28 is off for 15 seconds. Therefore, there is no load on the power supply, which is practically advantageous.

  In addition, an execution condition for determining whether or not to operate the load is provided, and the initial state detection means 26 capable of detecting whether or not the vehicle is in an initial state is provided. Even when the execution condition is not satisfied, the initial condition is satisfied. The vehicle load output control device 2 having the function of operating the load can operate the load when the initial conditions are satisfied without starting the engine at the time of shipment inspection at the factory, The operation of the load can be checked, and the usability can be improved.

  Furthermore, since the conventional 15-minute timer function can be used as it is, it can be realized without changing the configuration without increasing the cost, which is economically advantageous.

  The present invention is not limited to the above-described embodiments, and various application modifications are possible.

  For example, in the embodiment of the present invention, the rear defogger control and the deaiser control have been described. However, any battery load may be a problem, and it can be used for the control of the seat heater.
