Title: Microcomputer
Inventor: YOSHIOKA SHIRO
IPC: G06F1/04
Filed: 2000-02-21
Abstract: PROBLEM TO BE SOLVED: To continue the operation of prescribed processing as a set without generating the run-away of a CPU even when a noise intrudes into the power supply terminal of a microcomputer. SOLUTION: When a noise level is decreased to at least a small '1L' at the time of the intrusion of a noise, a register which stores significant information for deciding the state of a CPU is protected. Afterwards, when the noise level is increased to a '1H' level, a memory which stores significant information indicating the state of prescribed processing is protected. Moreover, when the noise level is increased to at least '2', the CPU is stopped. When the noise is decreased to less than '1L', the operation of the prescribed processing is continued by using the information preserved in the protected register and memory. Therefore, even when a noise intrudes, the generation of the run-away of the CPU can be prevented, and the prescribed processing can be temporarily interrupted and then continued.

Title: Rolling over determining method for vehicle
Inventor: MOMOHARA SHIGERO
IPC: B60R21/0132
Filed: 2000-03-17
Abstract: PROBLEM TO BE SOLVED: To improve the accuracy in determining the possibility of the rolling over by detecting the floating-up of one of left and right driving wheels of a vehicle from a road surface in determining the presence of the possibility of the rolling over of the vehicle on the basis of a rolling angle and a rolling angular speed of the vehicle. SOLUTION: A threshold value line S is determined on a two-dimensional map applying the rolling angle θ and a rolling angular speed ω of the vehicle as parameters, and the presence of the possibility of the rolling of the vehicle is determined when a hysteretic line of the actual rolling angle θ and the rolling angular speed ω crosses the threshold value line S from a non-rolling region at an origin side to a rolling region at a non-origin side.  When it is detected that one of left and right driving wheels is floated up from the road surface and idled at a high speed by the action of a differential gear, the threshold value line S is close to the origin side from a solid line position to a broken line position to allow the hysteretic line to easily cross a new threshold value line S', whereby the presence of the possibility of the rolling over can be judged earlier, and the performance of the air curtain can be effectively exercised.
