If the controller determines that the parking switch is OFF, the controller proceeds to step S103 and turns on the parking actuator 36. Turn off the operation.
In step S102, the controller determines whether or not the parking actuator 36 is currently operating. If it is operating, the controller proceeds to step S104. If not, the controller proceeds to step S105.

  When the process proceeds to step S104, the controller determines whether or not the engine throttle valve has been open for a predetermined time t1 or more for a predetermined angle θ1 or more. If the state where the throttle valve is opened by the predetermined angle θ1 or more continues for the predetermined time t1 or more, it is determined that the driver intends to start the vehicle, and the process proceeds to step S106, where the throttle valve is opened by the predetermined angle θ1 or more. If it does not continue for a predetermined time t1 or longer, the process proceeds to step S108 assuming that the driver does not intend to start the vehicle.

  When the process proceeds to step S106, the controller waits for a predetermined time t2, and then proceeds to step S107 to cancel the operation of the parking actuator 36. As a result, the vehicle can be started by the driver.

When the process proceeds to step S108, the controller determines whether or not the inhibitor switch that detects the operation of the brake lever is once turned off. When the controller switch is turned off once, the controller proceeds to step S109 and once. If it is not OFF, return.
When the process proceeds to step S109, the controller thereafter determines whether or not the inhibitor switch remains ON for a predetermined time t3 or more. If the controller switch continues, the process proceeds to step S107 and the parking actuator 36 is turned on. If the operation is canceled and not continued, the process returns. When the process proceeds from step S109 to step S107, the vehicle is switched from braking by the parking brake to manual braking.

  If the controller determines in step S102 that the parking switch is OFF and proceeds to step S105, the front and rear wheel speeds remain below the predetermined speed v in step S105 for a predetermined time t4 or longer. It is determined whether or not. When the state where the front and rear wheel speeds are lower than the predetermined speed v continues for the predetermined time t4 or longer, the process proceeds to step S110, and the state where the front and rear wheel speeds are lower than the predetermined speed v is not longer than the predetermined time t4. To return. In step S105, it is determined whether or not a low speed state in which the vehicle can be stopped continues for a predetermined time or more.

  In step S110, the controller determines whether or not the state where the throttle valve opening is equal to or smaller than the predetermined angle θ2 continues for a predetermined time t5 or more. If the state where the throttle valve opening is equal to or less than the predetermined angle θ2 continues for the predetermined time t5 or more, the process proceeds to step S111, and the state where the throttle valve opening is equal to or smaller than the predetermined angle θ2 continues for the predetermined time t5. If not, return. In step S110, it is determined whether or not the driver does not intend to start.

  In step S111, the controller determines whether or not the state where the inhibitor switch for detecting the operation of the brake lever is ON has continued for a predetermined time t6 or more. When the state where the inhibitor switch is ON continues for a predetermined time t6 or more, the process proceeds to step S112, where the parking actuator 36 is operated, and the state where the inhibitor switch is ON does not continue for the predetermined time t6 or longer. Will return.
