  • Patent number: 8218046
    Abstract: A video traffic system comprises a dual-slope, high dynamic range CMOS camera. Shutter, gain, and pedestal control and set-points for the dual-slope integration knee threshold and trigger time are computed from an operational model of the camera response using an input from a wireless light sensor. Darker pixels can integrate over the full shutter period, but bright pixels that are integrating too quickly and will saturate are reset to an adjustable level around 78% of maximum. Such reset occurs at an adjustable time about 93% of the full shutter period. The bright pixels are released to integrate from that point until the shutter closes.

  • Patent number: 7909970
    Abstract: An oxygen sensor is employed for determining whether the exhaust air-fuel ratio is rich or lean. A voltage is applied to the oxygen sensor at device impedance calculation intervals to calculate device impedance. After device impedance calculation, a reverse voltage is applied to the oxygen sensor with a view toward promptly negating the influence of voltage application on the sensor output. Subsequently, the sensor output of the oxygen sensor is sampled at sampling time intervals until it is concluded that the device impedance calculation period is over.

  • Patent number: 7434450
    Abstract: An air-fuel ratio sensor that outputs a sensor signal used for the feedback control of an air-fuel ratio is provided. It is determined whether an element crack is present by applying a reverse voltage to the air-fuel ratio sensor. The value of the sensor signal output from the air-fuel ratio sensor is corrected during a time period “A”. The time period “A” consists of a reverse-voltage application time period in which the reverse voltage is applied, and a return time period “T” after application of the reverse voltage ends. The return time period “T” is set based on sensor impedance correlated with the internal resistance of the air-fuel ratio sensor. The return time period “T” decreases as the sensor impedance decreases.

  • Patent number: 7340945
    Abstract: An air-fuel ratio sensor has an exhaust-side electrode and an atmosphere-side electrode. The atmosphere-side electrode is disposed in an atmosphere layer that communicates with the atmosphere. Since the air-fuel ratio sensor is disposed in an exhaust passage, exhaust gas enters the atmosphere layer if a sensor crack occurs. Ordinarily, forward voltage is applied to the air-fuel ratio sensor to obtain an output thereof in accordance with the air-fuel ratio. Immediately after the applied voltage is switched to reverse voltage, sensor current i1 in accordance with the impedance flows, regardless of the presence/absence of a sensor crack. After that, the sensor current converges to a value i2 that is in accordance with the oxygen concentration in the atmosphere layer. The presence/absence of a sensor crack is determined by comparing the value obtained by correcting i2 by i1, with a criterion value.

  • Patent number: 5394954
    Abstract: An engine control apparatus includes a first intake valve and a second intake valve provided along an intake passage. First and second actuators drive the respective throttle valves. A setting unit sets a vehicle target speed in the constant cruising speed control mode. A first control unit controls the first actuator so as to maintain the actual vehicle speed at the target speed during the constant cruising speed control mode. An angle sensor detects the angle of the first throttle valve. A mode memory stores information about a plurality of control modes to be used in controlling the second throttle valve. A mode selector selects one of the control modes. Each control mode stored in the mode memory defines the target angle of the second throttle valve that depends on the angle of the first throttle valve.
