Title: Onboard indicator controller
Inventor: MATSUBARA KATSUMASA
IPC: G09G5/00
Filed: 2002-06-19
Abstract: <P>PROBLEM TO BE SOLVED: To provide an onboard indicator controller capable of reducing power consumption of an indicator depending on the state of an onboard battery.  <P>SOLUTION: An ECU6 measures the output voltage of an onboard battery 8, and if it is below a prescribed voltage, shifts the operation mode of an indicator to a low power consumption mode. Thus, the duty ratio of a light-control pulse signal drops and the amplitude of video signal and common signal becomes smaller. When a current flows to a travel motor 9 even if the output voltage is equal to or above a prescribed voltage, the same instruction is issued. So, the power consumption of the indicator is reduced according to the state of the onboard battery.  <P>COPYRIGHT: (C)2004,JPO
