Title:
速度制限システム
Document Type and Number:
Japanese Patent JP2009536706
Kind Code:
A
Abstract:
A vehicle speed limiter is described, for use with, and for example fitted to, a vehicle throttle system (1) comprising a mechanically actuatable throttle member (3), an engine (10) speed controller (7), and a throttle signal unit in data communication with an engine speed controller and operably coupled to the throttle member so as to generate an electronic throttle signal in functional response to the degree of actuation of the throttle member, and to transmit a throttle signal to the engine speed controller whereby the engine speed is controlled. The speed limiter has a vehicle speed sensor (15) to obtain a signal indicative of vehicle speed; a limit speed data register to include a data store (17) for a data item indicative of at least a first predetermined limit speed; a comparator to compare the speed sensor output with the limit speed data item stored in the limit speed register; a throttle signal modifier unit acting on the output of a throttle signal unit in use when fitted in conjunction with a vehicle throttle system to modify a generated throttle signal so that a transmitted throttle signal is produced such as to tend to limit the vehicle to the applied limit speed. A method of fitment is also described.
