Title: Arithmetic method for lateral acceleration of vehicle
Inventor: ISODA KEIJI
IPC: B62D6/04
Filed: 1989-12-25
Abstract: PURPOSE:To calculate the lateral acceleration applied to the vehicle by using the speed difference between a left and a right driven wheel and the travel speed of the vehicle. CONSTITUTION:Sensors 26 and 27 find the speed difference Dv between the driven wheels 24 and 25 and the vehicle travel speed V by a TCL 22 to calculate ideal lateral acceleration which is free from the deformation of tires in consideration of the treads of the wheels. Then the TCL 22 corrects the ideal lateral acceleration Gr by using a correction coefficient K for variation in the effective radius of the left and right tires in turning to find real lateral acceleration G'r. The coefficient is obtained from experimental values. The TCL 22 instructs an ECU 13 to reduce the output of the engine 2 when G'r >= Gr1. A motor 17 reduces the opening extent of the throttle valve by a specific quantity to reduce torque and thus reduce the G'r. Further, the control is released when G'r is less then Gr2 which is much less than Gr1. This constitution speeds up driving control, neither rolling nor yawing is caused, and the steering stability is improved.

Title: Touch panel input method
Inventor: HANEDA ISAMU
IPC: G06F3/045
Filed: 1990-11-29
Abstract: PURPOSE:To clearly discriminate the input done by a pen from that done by a finger and to improve the input operability of a touch panel by detecting a touch position of the touch panel and the pressure applied to the touch position. CONSTITUTION:A display part 1 where a touch panel is put on a display substance is provided together with a keyboard part 2, and a built-in CPU. Then at least a touch position of the touch panel of the part 1 and the pressure applied to the touch position are detected by means of a fact that the high pressure is produced by a pen due to its thin point and the low pressure is produced by a finger due to its large area touching the panel respectively. When the first input is decided in a handwritten input area, the operation mode is changed to a pen input mode and only the pressure higher than a prescribed set level are read. Otherwise a finger input mode is set and the pressure lower than the prescribed level are read. Thus it is possible to clearly discriminate the pen input from the finger input.
