LIQUID DETECTION INSIDE A BATTERY TRAY TO AVOID BATTERY MALFUNCTION
A vehicle battery safety sensor system providing liquid detection inside a battery pack includes a battery pack having a structure defining a battery cell bay receiving a battery. A first sensor is mounted to the structure proximate to a low point area of the battery cell bay for sensing an operating condition within the low point area of the battery cell bay. A second sensor is mounted to the structure elevated above the first sensor for sensing an operating condition above the low point area of the battery cell bay. A safety module processes signals received from the first sensor and the second sensor and identifies if the operating condition within the low point area of the battery cell bay defines a fluid present in the low point area of the battery cell bay.
Secondary cell state detector
One-side plates of first and second condensers are connected to a one-side electrode of one of a plurality of secondary cells. First switches connect the other-side electrode of the secondary cell to the other-side plate of one of the first condenser and the second condenser. An MCU controls the first switches to connect the other-side electrode of the secondary cell to the other-side plate of the first condenser when the plurality of secondary cells is in a first state, and then connect the other-side electrode of the secondary cell to the other-side plate of the second condenser when the plurality of secondary cells is in a second state. A differential amplifier circuit outputs a differential voltage of voltages of the other-side plates of the first condenser and the second condenser. A cell monitoring IC detects states of the secondary cells based on the differential voltage.
OCCUPANT INFORMATION DETECTION SENSOR FOR STEERING WHEEL
Rim of steering wheel has a rim body and mounting component mounted to the rim body so as to be exposed from a portion of the rim body. Occupant information detection sensor for a steering wheel disposed in rim includes: sensor wire disposed in the rim body; and conductive member located on at least a surface side of mounting component and electrically connected or capacitively coupled with a portion of sensor wire.
CONTROL DEVICE AND CONTROL METHOD
A control device includes: an acquiring part that acquires a temperature of a battery cell of the battery; an identifying part that identifies a charge amount of the battery; and a cooling control part that determines a cooling-onset battery cell temperature on the basis of the charge amount identified by the identifying part, and operates an electric compressor to begin cooling the cooling water with the secondary refrigerant on condition that the temperature acquired by the acquiring part is higher than the determined, cooling-onset battery cell temperature. When the identifying part identifies a first charge amount, the cooling control part determines a higher cooling-onset battery cell temperature than in a case where the identifying part identifies a second charge amount that is higher than the first charge amount.
VEHICLE STEERING WHEEL
A vehicle steering wheel comprising:
a hoop,
a plurality of presence sensors, each one arranged so as to detect a proximity and/or contact between a user's limb and the hoop,
an outer sheath covering the plurality of presence sensors and stitched with at least one seam that extends around at least part of the hoop,
wherein the plurality of presence sensors is mounted on the same support, and in that at least one of the presence sensors is arranged facing at least part of the seam of the outer sheath.
PINCH SENSOR AND OPENING/CLOSING BODY CONTROL DEVICE
A pinch sensor that is provided with: a capacitive sensor electrode (18) that is provided to window glass; a shield electrode that covers a selected portion of the sensor electrode in a non-contact manner and that sets a limited detection directivity for the pinch sensor; and a dummy electrode that is arranged between the sensor electrode and the shield electrode and that is set to the same voltage as the sensor electrode or to a voltage that is in the vicinity thereof.
Secondary cell state detector
A condenser is connected to both electrodes of a secondary cell. A first switch is provided between a positive electrode of the secondary cell and a one-side plate of the condenser. An MCU turns ON the first switch when the secondary cell is in a first state to connect both electrodes of the secondary cell to both plates of the condenser, and then turns OFF the first switch. In addition, thereafter, the MCU detects a state of the secondary cell based on a differential voltage output from a differential amplifier circuit when the secondary cell is in a second state.
COLLISION DIAGNOSIS FOR A TRAFFIC EVENT
A collision diagnosis (12) is generated for a traffic event involving a vehicle, by receiving an output from a self-capacitance sensor (6) having a single electrode comprising at least part of the bodywork of the vehicle (3) and comparing the received output with at least one threshold (8) to generate provisional collision detection data (9). The provisional collision detection data (9) is correlated with further data (11) relating to the traffic event to produce correlation data and the collision diagnosis (12) is generated on the basis of the correlation data.
Hybrid vehicle
A hybrid vehicle includes an engine (10), a first motor generator (MG1), a second motor generator (MG2), a transmission unit (power transmission unit) (40), a differential unit (50), a clutch (CS) and a mechanical oil pump (501). The hybrid vehicle is able to switch between series-parallel mode in which power of the engine is transmitted via the transmission unit and the differential unit and series mode in which power of the engine is transmitted via the clutch. The differential unit (50) is a planetary gear mechanism including a sun gear (S2) connected to the first motor generator (MG1), a ring gear (R2) connected to the second motor generator (MG2), and a carrier (CA2) connected to a ring gear (R1) that is an output element of the transmission unit (40). The mechanical oil pump (501) is driven by power that is transmitted from the carrier (CA2) of the differential unit.
