Drawings
The various aspects of the present invention will become more apparent to those of ordinary skill in the art after reading the detailed description of the invention in light of the accompanying drawings. It should be understood by those skilled in the art that the drawings are designed solely for purposes of illustrating the subject technology in connection with the detailed description thereof and are not intended as a definition of the limits of the invention. Wherein,
fig. 1 is a schematic configuration diagram of an engine restart control system for a manual transmission vehicle according to an embodiment of the present invention.
Detailed Description
Embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
Fig. 1 is a schematic configuration diagram of an engine restart control system for a manual transmission vehicle according to an embodiment of the present invention. As shown in FIG. 1, an engine restart control system includes an information acquisition subsystem, a starter controller, and a starter. The information acquisition subsystem comprises a key position switch, a neutral gear switch, a clutch pedal bottom position switch, an engine rotating speed sensor and a whole vehicle network. The starter controller is capable of receiving a key position signal from a key position switch, an engine speed signal from an engine speed sensor, a gear signal from a neutral switch, a clutch pedal position signal from a clutch pedal bottom switch, and a vehicle speed signal from a vehicle network. The key position signal may include OFF (OFF position), ON (ON position), START (START position). The gear signal indicates whether the gear is in a neutral state. The clutch pedal position signal indicates whether the clutch pedal position is in a bottom position, i.e., whether the clutch pedal is fully depressed.
According to the embodiment of the invention, when judging that the engine is stalled, the starter controller can restart the engine by a signal sent by pressing the clutch pedal to the bottom or shifting the gear to the neutral position instead of starting the engine by screwing the key to the START position. Further, before restarting the engine, the starter controller will also determine whether the neutral switch and the clutch pedal bottom switch have failed, because the failed neutral switch and the clutch pedal bottom switch will make the restart unsafe, resulting in false operation of the starter.
In one embodiment, the starter controller is configured to:
when the engine is determined to be stalled, and the neutral switch and the clutch pedal bottom switch are determined not to have faults, the starter is controlled to enable the engine to be started in response to the gear signal indicating that the gear is in the neutral gear or in response to the clutch pedal position signal indicating that the clutch pedal position is in the bottom position, wherein,
when the key position signal is ON, the gear signal indicates that the gear is in a non-neutral gear, the clutch pedal position signal indicates that the position of the clutch pedal is not in a bottom position and the engine speed signal indicates that the engine speed falls to 0, the starter controller judges that the engine is stalled,
when the vehicle speed signal indicates that the vehicle accelerates under the action of an accelerator and the gear signal indicates that the gear is in a neutral gear, the starter controller judges that the neutral gear switch has a fault,
when the vehicle speed signal indicates that the vehicle accelerates under the action of an accelerator and the clutch pedal position signal indicates that the position of the clutch pedal is at the bottom position, the starter controller judges that the clutch pedal bottom position switch has a fault.
In another embodiment, a method of controlling engine restart for a manual transmission vehicle is disclosed, the method comprising the steps of: when the starter controller determines that the engine is stalled and determines that the neutral switch and the clutch pedal bottom switch are not in fault, the starter controller controls the starter to enable the engine to be started in response to the gear signal indicating that the gear is in neutral or in response to the clutch pedal position signal indicating that the clutch pedal position is in the bottom.
From the above description of the embodiments, those skilled in the art will appreciate that various modifications and substitutions can be made to the specific embodiments of the present invention without departing from the spirit and scope of the invention. Such modifications and substitutions are intended to be included within the scope of the present invention as defined by the appended claims.
