Engine systems which are easier starting and more resistant to degradation and discharge of their batteries are desirable in a wide range of equipment markets. The present engine systems utilize a selection module which selective switches from a first state when the battery is adequately charged to a second state which enables the use of auxiliary components such as special starting stators and regulators which can power the engine control module even when the battery is too discharged to power the engine control module directly.

An engine starter apparatus includes a starter motor, a temperature sensor configured to detect a temperature of the starter motor, a light source integrated with the starter motor, and a controller operatively connected to the temperature sensor and the light source. The controller is configured to illuminate the light source in a first color in response to the temperature of the starter motor exceeding a first temperature threshold. The controller is configured to illuminate the light source further in a second color in response to the temperature of the starter motor exceeding a second temperature threshold. The second temperature threshold is greater than the first temperature threshold. The first and second color are different. The second temperature threshold corresponds to a life limit of the starter motor. Illumination of the light source indicates an overheated starter motor, which may warrant a replacement of the starter motor.

An internal-combustion engine starting device includes a switch section, a motor section, a transmission mechanism section, and a pinion gear section, wherein the transmission mechanism section is configured of a planetary gear train including a pinion which is connected to the rotating shaft of the motor section, a plurality of planetary gears to which the rotation of the pinion is transmitted, and an internal gear which receives the rotation of the planetary gears; and of a machine casing in which is housed the planetary gear train, and wherein elastic bodies are each fitted between a protruding portion formed on the outer peripheral surface of the internal gear and a recessed portion in which to receive the protruding portion, and clearances are formed between the internal gear and the machine casing via the elastic bodies.

An automobile remote control power failure anti-theft device is provided, which relates to the technical field of automobiles and comprises: a control switch mounted on an automobile and configured to control on/off between an automobile circuit and an automobile power source; a remote switch connected to the automobile power source and the control switch for receiving an external control signal and controlling the on/off of the control switch according to the received signal; and an external controller disposed outside the automobile and wirelessly connected to the remote switch for facilitating carrying and controlling the remote switch to user. The above technical solution can not only remotely control on/off between the automobile circuit and the automobile power source, but also prevent the automobile from being stolen, and has the advantages of convenient on/off control of the automobile circuit, good control effect and good anti-theft effect.

An intelligent automotive component such as an engine starter. The intelligent automotive component having an power-link apparatus disposed within an housing comprising a circuitry that furthers allocates and restricts power supply to one or more components of the intelligent automotive component. The intelligent automotive component comprises an control apparatus such as an key fob that allows wireless communication between the intelligent automotive component and key fob.

A vehicle electric power supply apparatus includes a first electric power supply system, a second electric power supply system, an electric power fuse, a switch, a starter relay, an occupant operated unit, a starter control unit, and a switch control unit. The switch is controlled to be in one of an electrically-conductive state and a cutoff state. The starter relay is controlled to be in one of an electrically-conductive state or a cutoff state. The occupant operated unit is operated by an occupant. The starter control unit outputs an ON signal and the switch control unit outputs an OFF signal when the occupant operated unit is operated. The ON signal allows the starter relay to be controlled in the electrically-conductive state. The OFF signal allows the switch to be controlled in the cutoff state.

A sub-battery (33) having an internal resistance lower than that of a main battery (32) is connected to a power supply circuit (31) connected to the main battery (32). In this case, the sub-battery (33) is connected to the power supply circuit (31) after the voltage E.sub.CKT of the power supply circuit (31) is adjusted to the voltage E.sub.Sub of the sub-battery (33) by controlling the power generation voltage E.sub.ALT of an alternator (24) connected to the power supply circuit (31).

A method and system for operating a vehicle that includes feedback of operating status of an engine starting system is described. In one example, the method inhibits automatic engine pull-down in response to feedback from an engine starting system that does not meet expectations. The system and method may provide diagnostics for the engine starting system.

A method actuates a starter of an internal combustion engine by way of a starter relay. The starter relay is configured to supply the starter optionally with current via an on-board electrical system. The method has the following steps: determining an error status of the internal combustion engine; commencing repeated actuations of the starter relay; determining a current status of the internal combustion engine, wherein the current status of the internal combustion engine displays at least one error status or at least one operating status; and, if the current status displays at least one operating status, ending the repeated actuation of the starter relay, otherwise once again determining the current status. A system for actuating a starter of an internal combustion engine includes a control device, a power source, a starter relay, connected to the control device and configured to supply the starter of the internal combustion engine optionally with current from the power source via an on-board electrical system, wherein the control device is configured to carry out the method.

A vehicle power supply apparatus includes first and second power supply systems, an accumulator sensor, and an abnormality determination unit. The first power supply system includes a generator and a first electrical energy accumulator. The second power supply system includes a second electrical energy accumulator and a group of electric devices. The accumulator sensor detects at least a discharge current of the second electrical energy accumulator. The abnormality determination unit determines that the second electrical energy accumulator is abnormal on the condition that the accumulator sensor is normal and the discharge current of the second electrical energy accumulator is equal to or smaller than a current threshold.
