摘要： PROBLEM TO BE SOLVED: To conduct discharging control which satisfies the charging condition of a battery. SOLUTION: Voltages of respective battery blocks 50-1 to 50-n of a battery 50 are detected respectively by voltage sensors 70-1 to 70-n. A discriminating part 82 groups the battery blocks 50-1 to 50-n with the ones, the temperature of which are comparatively approximate to each other collected, and calculates the maximum voltage difference between the blocks in respective groups. A maximum value MAX(ΔVn) in a maximum voltage difference between the respective groups is taken out, which is compared with a first threshold. When it is equal to the first threshold or higher, the discharging amount of the battery 50 is restricted. When the MAX(ΔVn) turns into the second threshold or higher, the discharging of the battery 50 is stopped.

摘要： PROBLEM TO BE SOLVED: To provide a charging and discharging control device that can detect the charged state of a set battery properly taking the variation of the charged amount into account and can control charging and discharging properly. SOLUTION: The charged amount dispersion (oblique line area) between battery blocks constituting a set battery is detected. The variable range (A-B) of the charged amount is obtained by subtracting the detected dispersion value from the width between the upper and the lower limit value of the charged amount. Where the present charged amount (C, star mark) is positioned in the variable range is detected as a charged state. For instance, it is assumed that both ends of the variable range are 0% and 100%, and the variable range is used as a full scale. Then, the position of the charged amount on the scale is determined by a percentage ratio. The detection of the charging state is performed taking the dispersion of the charging state and the variation of the variable range into account and thereby, proper charging and discharging control is carried out based on the charged state.

摘要： PURPOSE:To obtain rubbing together between a brake pad and a brake rotor in an early stage, even when a brake force distribution giving priority to a regenerative brake force is adopted. CONSTITUTION:Rubbing together between a pad 30 and a brake rotor 28 is detected by ECU 16 based on the operation times of a hydraulic brake force, the total operation time of the hydraulic brake force, the wear of the pad 30, and the integration value of deceleration G, etc. Until a time when the rubbing together is detected, ECU 16 opens a hydraulic control valve 32 forcibly and exerts master cylinder pressure PM/C generated in a master cylinder 20 to the pad 20 as it is. After the detection of the rubbing together, ECU 16 controls the valve opening value of the hydraulic control valve 32 to a value equivalent to the maximum regenerative brake force of a motor 10 and also the brake force distribution is decided so that a required brake force can be obtained in hydraulic and regenerative total action.

摘要： PURPOSE:To omit a communication initializing line not used in a normal operation by jointly using the communication initializing line and the communication control line between communication equipments. CONSTITUTION:If a communication initializing signal is not sent to a request signal line 16, since a port P2 reaches an L level, a slave CPU 20 sends a request signal from a port P1. On the other hand, with the communication initializing signal sent to the signal line 16, since the level of the signal line 16 reaches the L level, a transistor 26 acting like an input buffer is turned off and the port P2 reaches an H level. Thus, the Q output of a FF 40 reaches an L level, interruption to the CPU 20 is generated and the CPU 20 executes the initializing processing of the communication part.

摘要： PURPOSE:To contrive the improvement of the accuracy of detection of an optical switch against an external disturbance light by providing a light emitting element driving circuit driving a light emitting element in terms of AC, a carrier detection circuit detecting a carrier of an AC frequency of the projecting light projected from the light emitting element, a DC component detection circuit and a deciding circuit deciding the on/off state of the switch. CONSTITUTION:An output signal V4 of a multivibrator 6 goes to a high level when a projecting light from a light emitting diode LD is received by a phototransistor PTR and goes to a low level when not received. An output signal V5 of a low pass filter 3 is compared with a reference voltage E2 by a comparator 5, and its output signal V6 goes to a high level when the signal V5 is lower than a reference voltage E2. A microcomputer 7 decides it in the switch-off state when the output signal V4 is at a high level and the signal V6 is at a low level, and decides it as the switch-on state when both the output signals V4, V6 are at a low level. Thus, it is prevented that the switch-on input is detected in error through the incidence of an external disturbance light.

摘要： PROBLEM TO BE SOLVED: To suppress the arrival of a battery storage amount at a lower limit in a hybrid vehicle.
SOLUTION: An error of a current measuring system having a current sensor 15 is previously evaluated, and set to a battery ECU 14. The battery ECU 14 offsets an integrated current in the case of estimating a battery charge storage amount by integrating the current measured by the sensor 15 to a discharge side by an error amount of the measuring system. Since the battery ECU 14 controls to charge or discharge so as to hold the estimated charge storage amount constant, in the case of offsetting to the discharge side, a control is operated to supplement it, and hence charging becomes superior to the case of conducting no offset. Thus, the arrival of the real battery charge storage amount at a lower limit of the battery charge storage amount is suppressed.

摘要： PROBLEM TO BE SOLVED: To detect abnormal temperature rise of a cell, by connecting in series temperature sensors whose electric resistance rapidly increases during a temperature rise, and measuring total resistance of the temperature sensors. SOLUTION: External lead wires 47, 48 are connected respectively with a minus terminal P and a plus terminal Q of a holding piece 43, and connected with a resistance measuring device 49. When at least one of 126 cells receives abnormal temperature rise, resistance of a PTC sensor 14 which is adhered to the cell increases extremely, and the resistance measuring device 49 detects the abnormality. Due to a simple structure in which number of external lead wires 47, 48 is limited, abnormal temperature rise of all cells in a cell source device can be detected. In addition, abnormal temperature rise detecting method and a device which maintain safety and do not cause heating problem of the temperature sensor are provided.
