| 20080238192 | POWER FEED CONTROL CIRCUIT FOR ON-VEHICLE ELECTRONIC CONTROL APPARATUSES - First and second on-vehicle electronic control apparatuses which communicate with each other through serial communication interface circuits are fed with powers through an output contact of a power source relay from an on-vehicle battery, an electromagnetic coil of the power source relay is energized through a transistor when a power source switch has been closed, first and second microprocessors are activated upon closure of the output contact, a first watchdog timer generates a self-holding command signal and keeps an operating state of the power source relay when intervals of a watchdog signal which is generated by the first microprocessor are normal, and the self-holding command signal is stopped to deenergize the power source relay, when the first and second on-vehicle electronic control apparatuses have completed their save processing steps in accordance with opening of the power source switch. | 10-02-2008 |
| 20080309163 | IN-VEHICLE MOUNT ELECTRONIC CONTROLLER - In an in-vehicle mount electronic controller, a constant-voltage power supply generates a high-precision small-capacity 5V output voltage Vad, a low-precision large-capacity 5V output voltage Vif and a low-precision large-capacity 3.3V output voltage Vcp, and also generates at least one of a low-precision small-capacity 2.8V output voltage Vup and a high-precision small-capacity 3.3V output voltage Vsb. A judgment signal input circuit logically combines comparison results of divided voltages of the above output voltages Vif, Vcp, Vup and Vsb with a divided voltage of the output voltage Vad as a reference voltage, and inputs relative voltage information ER | 12-18-2008 |
| 20090030587 | VEHICLE-MOUNTED ENGINE CONTROL APPARATUS - In an vehicle-mounted engine control apparatus according to the present invention, a restart inspection means, which is simpler than an activation inspection means, is provided, and a means to be applied is selected by an initialization determination means. The contents of the restart inspection are limited to malfunction items detected by a periodic code inspection means during driving of the vehicle. As a result, the time that is required to restart a microprocessor when a malfunction occurs is shortened. | 01-29-2009 |
| 20090134970 | IN-VEHICLE ELECTRONIC CONTROL APPARATUS HAVING MONITORING CONTROL CIRCUIT - An in-vehicle electronic control apparatus, having a monitoring control circuit, according to the present invention is configured in such a way that serial interface circuits | 05-28-2009 |
| 20090138137 | IN-VEHICLE ELECTRONIC CONTROL APPARATUS HAVING MONITORING CONTROL CIRCUIT - An in-vehicle electronic control apparatus having a monitoring control circuit is configured in such a way that a monitoring control circuit unit transmits question information from a logic circuit unit; a main control circuit transmits answer information generated by a microprocessor; the monitoring control circuit unit applies an addition and subtraction correction to the value of a first present-value memory by use of a first and fourth variation values Δ | 05-28-2009 |
| 20090312898 | IN-VEHICLE ELECTRONIC CONTROL APPARATUS HAVING MONITORING CONTROL CIRCUIT - A main control circuit unit | 12-17-2009 |
| 20100124024 | ELECTRONIC SUBSTRATE DEVICE - This invention is to provide an electronic substrate device which is capable of reliably and stably transferring heat generated by a heat generating component to a base member serving as a heat dissipater without intermediation of an electronic substrate. An electronic substrate device according to the present invention, in which a base member ( | 05-20-2010 |
| 20100149007 | ELECTRONIC CONTROL UNIT HAVING ANALOG INPUT SIGNAL - An analog input signal obtained from an analog sensor group | 06-17-2010 |
