Title: Method for detecting abnormality of anti-skid brake device
Inventor: TOTSUKA YUJI
IPC: B60T8/88
Filed: 1990-10-18
Abstract: PURPOSE:To prevent mistakes in detection of abnormalities by causing a device to judge wheel velocity sensors to be abnormal if the velocity of each wheel is judged to be abnormal in relation to pseudo vehicle body velocity and this abnormal state occurs at or above a predetermined low velocity area and continued for a predetermined time. CONSTITUTION:When a vehicle being operated is braked a controller 20 calculates pseudo body velocity according to wheel velocity signals from each wheel velocity sensor 19. The slip length SL of each driving wheel is calculated according to those values. It is then determined whether or not the absolute value of the slip length is larger than a predetermined value SL0, i.e., whether or not wheel velocity is abnormal in relation to the pseudo body velocity. When the absolute value is identified as being positive a subtraction timer is set and then it is deteremined whether or not the pseudo body velocity is more than a predetermined low velocity value (e.g. 20km/h) and when this value is also identified as being positive the slip length SL of each wheel is calculated again. Each slip length SL is compared to the predetermined value SL0 and when SL>SL0 a predetermined substraction value is subtracted from the value of the subtraction timer and an abnormality signal is output if the value obtained by this subtraction is at or below 0.

Filed: 1991-10-25
Abstract: PURPOSE:To reduce an amplification error and to obtain a high gain by connecting a differential transistor(TR) and a current mirror circuit in series and connecting a single folded cascode TR to the series connection point. CONSTITUTION:An input voltage Vi<+> is inputted to a base 41 of a TR1 and an input voltage Vi<-> is inputted to a base 42 of a TR2 and let a difference voltage be Vi. Let a current of a constant current source 1 be IB, then a current IB/2+i flows to the TR1 and a current Is/2-1 flows to the TR2. Moreover, a current IB/2+i+IB flows to a TR5 and the same current as a current flowing to the TR5 flows to a TR6 being a component of a current mirror 30 together with the TR5. Then a current flowing from a connecting point B to a folded cascode circuit 20 is a circuit 2i+IB being a current subtracting a current flowing to the TR6 from a current flowing to the TR5. When a current of a constant current source 3 is set equal to the current IB, the current flowing to a resistor RL is 2i and the voltage gain Av is expressed as Av=(hfe/hie.RL). The gain is equal to the gain Av of the differential amplifier comprising two TRs as a conventional amplifier.
