<p>PURPOSE:To prevent stoppage in a section to which power is not fed by deciding no power supply state of following power supply section during travel and applying brake if a decision is made during coasting operation that the following power supply section can not be passed through thereby forcibly stopping the vehicle. CONSTITUTION:A travel controller 15 detects a vehicle position at a position detecting section 16 based on a position signal fed from a position detector (not shown) and operates a vehicle speed at a vehicle speed detecting section 17. A memory 18 periodically receives information concerning to power supply to each power supply section and previously stored with information concerning to the length, gradient, traveling resistance, and the like of each power supply section. A section 19 decides power supply state of next pant supply section based on an output from the position detecting section 16 and information fed from the memory 18. When power is not fed to the next power supply section, the vehicle sustains traveling as it is if a section 20 makes a decision that the vehicle can coast through the next power supply section, otherwise brake is applied to stop the vehicle forcibly. Consequently, the vehicle is prevented from stopping in a section not supplied with power and thereby recovery work is facilitated.</p> |
