A sensor disposition structure in a seat includes a cushion pad and a board-like member which is disposed under the cushion pad. A concave is formed in an upper surface of the board-like member, and a sensor is disposed in the concave.

In a collision detection device for a vehicle, the bumper absorber includes general parts and holding parts alternately in a lengthwise direction of the groove portion. In each of the general parts, a predetermined clearance is formed between an inner wall surface of the groove portion on at least one side of vehicle up and down sides, and the detection tube member. Each of the holding parts is in contact with a surface of the detection tube member on at least one side of vehicle up and down sides, and vehicle front and rear sides to hold the detection tube member. A holding part ratio, which is a ratio of a part of the detection tube member held by the holding parts to a unit length of the detection tube member, is set to be smaller than a predetermined value.

Various machines, systems, and methods for generating calibration data for a sensorized brake pad are disclosed. In some embodiments, a system includes a fixture, a brake pad retainer, a pressure plate, an actuator and a controller. The actuator applies a pressure to the sensorized brake pad and signals from the pressure sensors are received. Calibration data is generated based on the signals received from the pressures sensors when the pressure is applied to the sensorized brake pad.

A fuel tank system including a fuel tank internally storing fuel, a canister in which vaporized fuel generated in the fuel tank is adsorbed and desorbed by an adsorbent, and open to the atmosphere by an atmosphere communication pipe, a purging pipe placing an engine in communication with the canister, a vent pipe placing the fuel tank in communication with the canister, a negative pressure pump provided at the atmosphere communication pipe, causing negative pressure to act on the fuel tank from the canister, and a negative pressure open/close valve provided at the vent pipe, maintaining an open state at a pressure difference between a negative pump pressure acting from the negative pressure pump and a tank internal pressure acting from the fuel tank, and closing at a pressure difference between a negative purging pressure acting from the engine and the tank internal pressure.

A driving system for a vehicle includes an engine including a fuel injection valve, an electric motor, a hydraulic clutch which connects/disconnects the engine to/from the motor, a hydraulic pressure sensor which detects hydraulic pressure of the clutch, and a controller which selectively executes one of a motor travel mode where the motor is activated and the engine is stopped, and an engine travel mode where at least the engine is activated. In a startup of the engine accompanying a change from the motor travel mode to the engine travel mode, the controller causes the clutch to transition from a disconnected state to a connected state, determines the connected state of the clutch based on hydraulic pressure detected by the hydraulic pressure sensor, and when the clutch is confirmed to be in a predetermined connection initial state, the controller causes the fuel injection valve to inject fuel.

An engine device including a post-treatment device 20, provided in an exhaust passage of an engine 1, for purifying an exhaust gas from the engine 1. As the post-treatment device 20, a three-way catalyst 22 is used. The engine device further includes a filter case 31 including a filter body 32 for catching deposits in the exhaust gas. The filter case 31 is disposed, in a replaceable manner, upstream of the post-treatment device 20 in the exhaust passage.

A fuel storage assembly for a vehicle includes a fuel tank defining a fuel chamber, a fuel pump module and a vapor pressure detection system. The fuel pump module includes a flange engaged to the fuel tank and a fuel pump assembly supported by the flange and disposed in the fuel chamber. The vapor pressure detection system includes a vapor pressure sensor attached to the flange, a vapor pressure inlet device disposed in the fuel chamber, and a conduit communicating between the vapor pressure inlet device and the vapor pressure sensor.

The present invention provides a hybrid vehicle, including a power battery, a fuel storage tank, an electrical power generation unit, a pressure detection unit and a work mode controller, and adopts a pressure protection mode under the work mode controller, wherein the work mode controller is configured to control the vehicle to enter the pressure protection mode when the electrical power generation unit is in a stop state and when the gas pressure detected by the pressure detection unit is higher than a pressure threshold; and in the pressure protection mode, the electrical power generation unit is started from the stop state to enter the working state to consume the fuel in the fuel storage tank, and the gas pressure in the fuel storage tank is accordingly reduced. As the pressure protection mode is adopted in the present invention, the electrical power generation unit can be automatically started according to the gas pressure of the fuel in the fuel storage tank to charge the power battery using the expanded redundant fuel. The safety problem and the waste resulting from the fact that the expanded fuel exceeding the threshold in the fuel storage tank is discharged into the atmosphere in the prior art are avoided.
