The user-activated secondary switch makes a connection in a parallel electrical power supply circuit to the engine and vehicle accessory drive, when the secondary switch is in the CLOSED state. The control logic circuit is responsive to the ignition switch, the secondary switch, and a user-activated vehicle control device. The third switch is associated with a user-activated vehicle control device wherein the third switch causes the logic circuit to interrupt the parallel electrical power supply circuit, when the user-activated vehicle control device is activated.Type: GrantFiled: May 9, 2006Date of Patent: September 22, 2009Assignee: Safe Stop International, LLCInventors: Charles Barroy Brown, Jr., Michael Joseph Trebilcott, Jr.

Patent number: 7570138Abstract: An electromagnetic switch for a starter comprises a current-supply terminal and a vibration absorber configured to absorb vibration imposed on the terminal. The terminal is provided so that one end of the terminal is tightly attached to the switch, and the other end is connected to a cable which supplies electric current to the switch. One end of the terminal is tightly attached to a bobbin wound by an excitation coil to which the current is supplied and the other end protrudes through a molded cover outward to be connected to the cable at a connection port formed in the molded cover. The vibration absorber is, for example, a bent portion of the terminal formed integrally with the terminal itself. One or more flexible members are attached to the terminal to support the terminal within the electromagnetic switch and to seal inner spaces between the terminal and the switch.Type: GrantFiled: December 19, 2005Date of Patent: August 4, 2009Assignee: Denso CorporationInventor: Takashi Hirabayashi

Publication number: 20090134700Abstract: In a power supply system, a controller is electrically connected with a plurality of switching elements of a multiphase inverter. The controller switches the plurality of switching elements on and off during a multiphase motor being activated. This converts a voltage of a first power storage device into a multiphase AC voltage so as to supply the multiphase AC voltage to the multiphase motor. This also boosts a voltage of a second power storage device to charge the first power storage device by the boosted voltage via multiphase windings of the motor. The controller switches the plurality of switching elements on and off during the multiphase motor being inactivated to thereby boost the voltage of the second power storage device to charge the first power storage device by the boosted voltage.Type: ApplicationFiled: November 20, 2008Publication date: May 28, 2009Applicant: DENSO CORPORATIONInventors: Katsunori Tanaka, Yukari Tanaka, Makoto Taniguchi

Publication number: 20090108674Abstract: When an ignition key is turn ON, an ECU drives a bidirectional DC/DC converter to charge a capacitor to a voltage Vth1. The ECU turns on a first relay only and diagnoses whether or not a second relay, which is off, is welded, based on a change in a voltage VL at that time. After the diagnosis on welding, the ECU turns on the second relay, and the capacitor is charged to a voltage level of a main power storage device.Type: ApplicationFiled: April 23, 2007Publication date: April 30, 2009Applicant: Toyota Jidosha Kabushiki KaishaInventors: Masahito Ozaki, Kenji Uchida, Hisato Nishida
