A method for monitoring an engine starting system includes detecting a first engine crank command, monitoring engine speed states, and collecting the engine speed states in a first buffer disposed in a first controller. A second engine crank command is determined based upon monitored electric power states from a battery. The electric power states from the battery are collected in a second buffer disposed in a second controller. The engine speed states collected in the first buffer are synchronized with the electric power states from the battery collected in the second buffer based upon the first engine crank command and the second engine crank command. A starter resistance is determined based upon the electric power states from the battery. A telematics device communicates the starter resistance and the monitored engine speed states synchronized with the monitored electric power states to a remote system.

In an engine control device, an automatic engine stop control section automatically stops an engine operating when an automatic engine stop condition is satisfied. An engine start control section supplies electric power to a starter to drive the starter when receiving an initial engine start intention signal transmitted from a push starter and when an automatic engine start condition has been satisfied. An engine start completion detection section detects whether the engine start of the engine has finished. An automatic engine stop permission section permits the automatic engine stop control section to stop the engine operating when the automatic engine stop permission section detects that the engine start has finished at a timing when the engine start control section has started the engine after receiving an initial engine start intention detection signal transmitted from the push starter.

A control unit is provided for controlling a vehicle including a platform for carrying a load and an engine system for controlling an engine of the vehicle, wherein the control unit is configured to receive a signal, from at least one weight indication means of the vehicle, the signal being indicative of a weight of a load on the platform; compare the received indicated weight of the load on the platform with a predetermined threshold value. The control unit is further configured to provide an engine start-up signal to the engine system of the vehicle if the received indicated weight of the load on the platform is above the predetermined threshold value.

An apparatus for controlling a startup of an engine includes an engine, an engine controller configured to check whether the startup of the engine is prepared to generate information on whether the startup is prepared when an ignition is turned on, a hybrid controller configured to check whether communication with the engine controller is normal and to generate information on whether the hybrid controller is normal, the hybrid controller causing a vehicle to be driven only in an EV mode or generating a start control signal for the startup of the engine, according to whether the EV mode is engaged when a start signal is input from a driver, and a starter driver configured to start the engine in response to the start control signal.

A hybrid vehicle control device is provided for controlling a drive system in a hybrid vehicle. The hybrid vehicle control device is provided with a hybrid control module that controls an operation start timing of a DC/DC converter at vehicle startup. When an ignition switch is pressed, after connecting a high power relay that is interposed between the motor/generator and the high power battery, the hybrid control module starts operation of the DC/DC converter upon determining that the outputtable electric power by the high power battery is a prescribed value or greater.

A vehicle control apparatus is provided that can maintain an automatic engine stop function when an abnormality occurs in a preceding vehicle following control function. The vehicle control apparatus includes a first control unit configured to include a preceding vehicle following control function to control vehicle speed, based on a traveling state of a preceding vehicle, and to output a prohibition request to an automatic engine stop function; and a second control unit configured to include the automatic engine stop function, and to maintain the automatic engine stop function, contrary to the prohibition request output from the first control unit, when an abnormality occurs in the preceding vehicle following control function.

A method for controlling a vehicle power train that includes a heat engine connected to the transmission of the vehicle by a clutch controlled between an open position and a closed position of the transmission by a computer of the transmission exchanging information with a computer of the heat engine. The method includes sending, in order to shut down the engine before the clutch is opened when the vehicle is in motion, the kinematic chain being closed and the injection interrupted, a message from the computer of the transmission to the computer of the engine at a first moment in time so as to synchronize an opening of the clutch and the closure of an air flap of the engine at a second moment in time subsequent to the first moment.

Embodiments of systems and methods for starting an electronically controlled engine of a TRS by supplying power from a battery, are provided. The engine is electronically controlled by an engine control unit (ECU). The systems and methods can achieve a complete engine start even when the ECU experiences a reset during the startup of the engine.

A control system for a plug-in hybrid vehicle includes a drive system including a starter motor, a transverse engine, and a motor/generator, and a power supply system including a high voltage battery, a capacitor, and a hybrid control module that controls charging and discharging of the capacitor. In the control system for an FF plug-in hybrid vehicle in which an external charging of the high-power battery is available, the hybrid control module starts the starter, performs mode selection control and charge/discharge control, maintains a capacitor voltage at or below a deterioration free voltage when the CS mode is selected during ignition on, and recharges the capacitor to a starter start-up permission voltage that allows the starter to start when a pre-forecast of the reverse transition from the CS mode to the CD mode is established.
