A maximum value of a discharge current from a capacitor 13, detected by a primary-side current detection means 24 disposed at a grounded end of the capacitor 13, is controlled such as not to exceed a predetermined first control value Y1. The first control value Y1 is derived based on magnetic saturation of a primary winding 3, with the control being performed by controlling the on-off state of an energy injection switching means 20. As a result, magnetic saturation of the primary winding 3 can be prevented, and the reliability of an ignition apparatus which incorporates an energy injection circuit 6 can be increased.

Upon a valve rotation angle of a flow rate control valve (15) exceeding a radiator-flow-path closed position during changing of the valve rotation angle of the flow rate control valve (15) in an opening direction of a radiator flow path (16) from a closed state of the radiator flow path (16), a cooling water starts to circulate through the radiator flow path (16), and an outlet water temperature or an inlet water temperature of an engine (11) starts to drop. The radiator-flow-path closed position is learned as a valve rotation angle of the flow rate control valve (15) immediately before the outlet water temperature detected by an outlet water temperature sensor (22) or the inlet water temperature detected by an inlet water temperature sensor (23) starts to drop during changing of the valve rotation angle of the flow rate control valve (15) in the opening direction of the radiator flow path (16) from the closed state of the radiator flow path (16). Consequently, a malfunction caused by a variation in the radiator-flow-path closed position of the flow rate control valve (15) regulating a cooling-water flow rate in the radiator flow path can be restricted.

In an engine (10), an intake duct (11) is provided with an intercooler (34) disposed downstream of an intake air compressor (31). An EGR pipe (36) is provided with an EGR valve (37) and an EGR cooler (38). An ECU (50) determines a generation of a condensed water in the EGR cooler (38), the generation of the condensed water in a merging portion where a fresh air and an EGR gas merge with each other, and the generation of the condensed water in the intercooler (34). When it is determined that the condensed water is generated in any of these portions, the ECU (50) performs a corresponding countermeasure for restricting the generation of the condensed water.

A NOx concentration measurement system has a NOx sensor 2, a detection section 3, a NH_(3) concentration estimation section 5 and a calculation section 7. The NOx sensor 2 measures a sum concentration c_(4) of a concentration of NOx (a concentration c_(1) of combustion derived NOx) in exhaust gas g, and a concentration of NO (concentration c_(3) of derived NO which has been derived from NH_(3)) oxidized from NH_(3). The calculation section 7 calculates the concentration c_(3) of derived NO by using a concentration c_(2) of NH_(3) contained in outside exhaust gas which is present around the NOx sensor, not inside of the NOx sensor, and at least one of an air fuel ratio A/F, a concentration of O_(2) and a concentration of H_(2)O. The concentration c_(1) of the is calculated based on the sum concentration c_(4) and the concentration c_(3) of derived NO.

Load sensors 4FR, 4RR, 4FL, 4RL are disposed on four corners of a seat cushion. An occupant decision section 51 of an occupant detection ECU 5 decides a type of an occupant BH on a vehicle seat based on loads Wfr to Wrl detected by the load sensors 4FR to 4RL. A CRS changing section 53 that prohibits the occupant decision section 51 from changing a decision to a decision result that an adult is seated in the vehicle seat and changes the decision to a decision result that a child seat is attached on the vehicle seat when an engagement of a tongue plate with a buckle of a seat belt device is detected by a buckle switch 3 and a buckle load Wb calculated by buckle load calculation section 54 is less than a predetermined buckling load threshold Wbth1, Wbth2 in a case where the occupant decision section 51 decides that an adult is seated in the vehicle seat.

A parking assist system includes an electronic control unit (14) configured to: estimate first extending directions of obstacles respectively located on right and left sides of a target parking space in a state where a host vehicle moves across in front of the target parking space; calculate a planned moving path based on the estimated first extending directions; as the host vehicle is guided into the target parking space, estimate second extending directions of the obstacles respectively located on the right and left sides of the target parking space while updating the second extending directions; determine whether the estimated and updated second extending directions satisfy a predetermined condition; and when the updated second extending directions satisfy the predetermined condition, update the planned moving path by using the updated second extending directions instead of the first extending directions or the second extending directions before being updated.


In a system, an angle sensor outputs a pulse each time an output shaft of an internal combustion engine rotates by a preset angle, and a calculator calculates speed-change information indicative of a change in a speed of rotation of the output shaft based on the pulses outputted from the angle sensor. A determiner determines, based on the speed-change information, whether at least one of the pulses outputted from the angle sensor represents a proper timing for a preset of a pinion of a starter with a ring gear mounted on the output shaft. A pinion engaging unit shifts the pinion toward the ring gear so that the pinion is engaged with the ring gear when it is determined that the at least one of the pulses outputted from the angle sensor represents the proper timing for the preset of the pinion with the ring gear.

A heat exchanger has (i) a first passage (45) in which a first fluid flows, (ii) a heat storage body (41) that is thermally connected to the first passage (45) and stores a warm heat or a cold heat, and (iii) a second passage (46) that is thermally connected to both of the first passage (45) and the heat storage body (41), the second passage in which a second fluid flows. The heat exchanger performs a heat exchange between the first fluid and the second fluid. The heat storage body (41) changes to a first phase in a solid state when a temperature of the heat storage body (41) is lower than or equal to a phase transition temperature, and changes to a second phase in a solid state when the temperature of the heat storage body (41) exceeds the phase transition temperature. The heat storage body (41) stores or dissipates heat depending on a phase transition between the first phase and the second phase. The second passage (46) is formed in the heat storage body (41) integrally with the heat storage body.
