Title: Driving force control device for vehicle
Inventor: MAEDA SHINICHI
IPC: F02D45/00
Filed: 1991-10-25
Abstract: PURPOSE:To prevent an apparent accelerated slip state during deceleration of a vehicle so that driving force control is not performed during deceleration, when the false accelerated slip state is detected by employing a previously calculated average front wheel speed as a new front wheel speed. CONSTITUTION:When it is judged by a first wheel speed comparing means 132 that a previous average front wheel speed Vf (n-1) stored in an average previous front wheel speed value storage means 134 is larger than a front wheel speed Vfw (n), and it is judged by a second wheel speed Vrw (n), it is judged that a vehicle is in a false slipped state during deceleration. In this case, the average front wheel speed is not calculated by a calculating means 131, and the previous Vf (n-l) is employed as a new average front wheel speed Vf (n) and outputted to a slip-amount calculating means 310 together with an average rear wheel speed Vrw (n). Thus, the degree of a false accelerated slip state is reduced, and thus driving force control is not performed.

IPC: G11C11/40
Filed: 1986-12-23
Abstract: PURPOSE:To attain high speed write by giving a low potential to the gate of a pull-up FET only at write to the bit line so as to limit a pull-up current. CONSTITUTION:A write control signal, the inverse of C is inputted to the gate of a pull-up FET (T1, T2) in a GaAs memory. The signal represents a NOR logic between a Y decoder and the AND of a write enable signal WE. In the case of the write to a column Y, the FET (T1, T2) is turned off to suppress the pull-up current and information is written accurately at high speed onto bit lines B, and the inverse of B. In the case of write to other column, the pull-up FF is turned on and the bit line amplitude is kept small, then the quick readout is attained at the next readout cycle. Similarly, a large pull-up FET is turned on at readout to supply a large pull-up current for high speed readout.
