Abstract:
A safety device for a remotely-activated power supplying system of a manual transmission vehicle,the manual transmission vehicle including a key-operated power supplying system capable of being activated through an ignition key, an ignition system connected electrically to the key-operated power supplying system, a handbrake, and a gear shift lever, the remotely-activated power supplying system including a power supplying device to be connected to the ignition system, a main controller connected to the power supplying device, a wireless receiver connected to the main controller, and a wireless transmitter operable so as to transmit a start signal to be received by the main controller through the wireless receiver, said safety device comprising: a starting safety unit adapted to be connected to the main controller for detecting presence of a safety condition, said starting safety unit including at least one of a handbrake detector adapted to detect position of the handbrake, and a lever detector adapted to detect position of the gear shift lever, the safety condition being at least one of the handbrake being disposed at a parking position and the gear shift lever being disposed at a neutral gear position, an ignition key detector adapted to be connected to the main controller and adapted to detect if the ignition key is uprooted from the key-operated power supplying system, wherein said ignition key detector has an input adapted to be connected to the key-operated power supplying system, and an output adapted to be connected to the main controller, said ignition key detector being adapted to indicate a deactivated status of the key-operated power supplying system to the main controller when the ignition key is uprooted from the key-operated power supplying system, further wherein said ignition key detector includes a voltage dividing circuit, said voltage dividing circuit including a first resistor having opposite terminals connected to said input and said output, respectively, and a second resistor having a first terminal connected to said output and a grounded second terminal, and whereby, the main controller is configured to activate the power supplying device to permit supply of electric power to the ignition system for a preset time period when the start signal is transmitted by the wireless transmitter and is received by the main controller through the wireless receiver, when the safety condition is detected by said starting safety unit, and when said ignition key detector detects that the ignition key is uprooted from the key-operated power supplying system.
