摘要： A gas concentration measuring apparatus for use in air-fuel ratio control of automotive engines is designed to determine the concentration of oxygen within a wide and a narrow range using a sensor current flowing through a sensor element. The apparatus includes an amplifier circuit equipped with an operational amplifier and a plurality of amplifying resistors and a switch. The switch is responsive to a request signal to switch a relation in electrical connection between an operational amplifier and the amplifying resistors to distribute the amplifying resistors into an input resistor and a feedback resistor for the operational amplifier to change an amplification factor of the amplifier circuit. This results in a change in resolution of measurement of the concentration of oxygen, thereby ensuring enhanced accuracy in determining the concentration of oxygen in a selected one of the narrow and wide ranges.

摘要： An air-fuel ratio sensor is equipped with a sensing element including a solid electrolytic substrate. When the sending element is warmed up and activated by a heater, a microcomputer controls electric power supplied to the heater based on a control base value being set according to a duty ratio=100%. A power profile P1 is determined beforehand to set a target heater power. Through the warm-up heater power control, an actual heater power supplied to the heater is equalized to the target heater power determined according to the power profile P1.

摘要： A gas concentration measuring apparatus is provided which may be employed in measuring an air-fuel ratio of mixture sucked into automotive engines. The apparatus includes a gas concentration sensor exposed to a gas and a voltage applying circuit. The gas concentration sensor is responsive to application of voltage to produce a current signal indicative of concentration of the gas. The voltage applying circuit includes an operational amplifier which operates on a source voltage and which outputs the voltage for developing the voltage applied to the gas concentration sensor which has a level changing as a function of voltage inputted to the operational amplifier. The operational amplifier is designed to have an amplitude of each of the voltages inputted to and outputted from the operational amplifier which falls within a given input/output voltage range defined between an upper limit and a lower limit of a source voltage range and near at least one of the upper and lower limits of the source voltage range, thereby allowing the air-fuel ratio to be measured with higher accuracy over a wide range.

摘要： The accuracy of determination of a possibility of collision of a vehicle with an object is enhanced without the shortening of a period for detection of the object by an object detecting apparatus. A collision-possibility determining device determines the presence or absence of a possibility of collision of the vehicle with the obstacle by comparing a future locus of movement of the obstacle determined by an obstacle locus determining device based on an output from a radar device, with a future locus of movement of the vehicle determined by a vehicle locus determining apparatus based on outputs from wheel speed sensors and a yaw rate sensor. The period of the detection conducted by the radar device providing data about the obstacle to the obstacle locus determining apparatus is 100 msec, but the obstacle locus determining apparatus, the vehicle locus determining apparatus and the collision-possibility determining apparatus carry out the determination of the possibility of collision at a determination period shorter than the detection period of 100 msec. Thus, it is possible to carry out the determination of the possibility of collision at the shorter determination period without use of a large-sized and expensive radar device, thereby enhancing the determination accuracy.

摘要： In a vehicle safety running system, while a contact probability estimation section estimates that there is a probability that a subject vehicle comes into contact with an object and an automatic braking section performs automatic braking, when the driver voluntarily performs a steering operation to avoid the contact, an automatic braking cancellation gradient is calculated based on the contact probability detected with the contact probability estimation section and the steering operation amount detected with the steering operation amount detection section, whereby automatic braking is cancelled at a speed corresponding to the automatic braking cancellation gradient so calculated. When the contact is easily avoided through the steering operation, the automatic braking cancellation gradient is set large so as to cancel automatic braking quickly, while when the contact is difficult to be avoided, the automatic braking cancellation gradient is set small so as to cancel automatic braking moderately.

摘要： A vehicle travel safety device carries out automatic braking in order to prevent a subject vehicle from coming into contact with an object, and proximate expansion of an air bag is reliably prevented. When there is a possibility of a subject vehicle coming into contact with an object, automatic braking is carried out in order to prevent the contact. If a seat belt wear state sensor detects that an occupant is not wearing a seat belt and an air bag expansion possibility estimating means estimates that there is a possibility of an air bag expanding, by means of an automatic braking means, the deceleration rate of the automatic braking is reduced so that the occupant is prevented from moving forwards due to the inertia accompanying the braking and causing proximate expansion. When the speed of the subject vehicle at the time when automatic braking is started is high, the relative speed between the subject vehicle and the object at the time when automatic braking is started is high. Thus, the time taken for the subject vehicle to come into contact with the object is short or the speed of the subject vehicle at which it will come into contact with the object is high. Therefore, the air bag expansion possibility estimating means estimates that there is a possibility of the air bag expanding.
