Embodiment Construction

[0013] Such as figure 1 As shown, a CPU (Central Processing Unit) 3 as a controller is mounted on a vehicle (not shown). The collision detection signal from the collision detection determination device 2 and the collision prediction signal from the pre-collision sensor 4 are input into the CPU 3 so that the CPU 3 processes the collision detection signal and the collision prediction signal. Then, the CPU 3 outputs control signals to the motor drive control device 5 and the engine drive control device 6 . In addition, diagnostic information from control devices as the hybrid control system, hybrid battery control system, and engine control system is input into the CPU 3 . The CPU 3 processes the diagnostic information, and then outputs the processing result as a calculation result based on the diagnostic information to the motor drive control device 5 and the engine drive control device 6 .

Abstract

An in-vehicle apparatus for a vehicle driven by a first driving power source in a first driving mode and driven by a second diving power source in a second driving mode, includes: a collision detection device; a stopping device stopping the first and second driving modes when the collision detection device detects collision; a severity determination device determining a severity of collision indicative of a collision intensity; and a controller. Under a condition that the stopping device stops both of the first driving mode and the second driving mode, the controller executes one of recovery of both of the first driving mode and the second driving mode, recovery of one of the first driving mode and the second driving mode, and system shut-down according to the severity of collision.

Description

technical field [0001] The present disclosure relates to an in-vehicle device for detecting a collision of a vehicle having a first driving mode using a first driving source and a second driving mode using a second driving source so that the device responds to the collision. Background technique [0002] There are a variety of crash configurations for a vehicle colliding with another vehicle or object. The collision may trigger leakage of electric power supplied to an electric motor as a drive source of the vehicle or leakage of fuel supplied to an internal combustion engine as a drive source of the vehicle. [0003] Conventionally, in order to prevent electric shock or misfire caused by leakage of electric power or fuel leakage, the power supply for the driving source is turned off according to a collision detection signal output from a collision detection sensor such as an acceleration sensor or according to a collision detection signal from an airbag ECU , or cut off the...
