Description

  The present invention relates to an engine starting device that permits starting of an engine on the condition that an ID code from a transmission means is determined to be a registered regular one.

  In order to prevent theft of vehicles that frequently occur in recent years, the vehicle includes a transmission unit that can transmit a vehicle-specific ID code while being carried by a driver, and a reception unit that can receive the ID code. A so-called smart entry system has been proposed that allows various operations of the vehicle including engine start, provided that the ID code is genuine. For example, in the case of a smart entry system in a two-wheeled vehicle, when a driver carrying a portable device (transmitting means) accesses, an ID code transmitted from the transmitting means is received by a receiving means installed on the vehicle side and registered in advance. It is determined whether or not the engine is genuine, and the engine start operation is enabled only when the engine is genuine.

  In addition, motorcycles equipped with the smart entry system as described above conventionally have an operation knob that can be rotated on the condition that it is determined that a proper ID code has been received, and the operation knob can be rotated. Thus, an ignition switch device has been proposed in which the engine can be started (see, for example, Patent Document 1). In such an ignition switch device, an operation knob can be turned from an off position to an on position or a lock position, and the start of the engine is permitted at the on position, and the bar-type handle provided in the vehicle at the lock position. Is configured to lock.
