PROBLEM TO BE SOLVED: To prevent the starts of electrical loads from being overlapped with each other. SOLUTION: This electrical load controller comprises a VSC device in which a predetermined rush current generated when the device is started for a TA period, an AHC device started after a T1 period is passed after a notice signal for notifying of the start beforehand to the VSC device, and a start request means for requesting the start of at least the VSC device of the VSC device and the AHC device. A communication time between the AHC device and the VSC device is T2. T1 is longer than T2, and TA is shorter than the value obtained by deducting T2 from T1. The VSC device is promptly started when the start notice signal is not received by the VSC device when the request of the start is made from the start request means to the VSC device.

PROBLEM TO BE SOLVED: To aim at suppressing delay variations to the minimum and realizing transmitting and receiving of data through a gateway, without being accompanied by a big delay in relation with a network system. SOLUTION: A plurality of networks 14 and 16 to which nodes 12 are connected, respectively, are connected through the gateway 18. At every networks 14 and 16, two network busses 20, 22, or 24 and 26 are provided to which each node 12 and a gateway 18 of the networks 14 and 16 are connected. One network bus 20 or 26 is used as transmitting and receiving bus which makes the data transmitting and receiving between the nodes 12 or between the node 12 and the gateway 18. And, the network bus 22 or 24 of another side is used as receiving dedicated bus which makes the node 12 receiving data from the gateway 18. COPYRIGHT: (C)2006,JPO&NCIPI
Abstract:
PROBLEM TO BE SOLVED: To efficiently and precisely detect a bug of a compiler. SOLUTION: The same input value is given to a plurality of machine language programs 5 and 7 operating in operating environments different from each other generated by a plurality of compilers, and output data (a) and (b) being the output values of them are compared so that the bug of the compiler can be indirectly detected. In this case, since possibility of presence of the completely same bug is extremely low in the respective same parts of the two kinds of compilers, the presence of the bug of any one compiler can be estimated from the presence of the mismatch of the output results.

Abstract:
PURPOSE:To prevent the amount of roll control from becoming excessive to avoid the generation of back roll by reducing-correcting a steady roll angle to small values when the coefficient of friction becomes smaller enough for the wheels to be likely to slip on the road surface. CONSTITUTION:Flow control valves B and opening and closing valves C correspendingly are controlled by an electron control device 102 to control the road clearance and roll of a vehicle body based on signals from road clearance sensors 87-90, a steering torque sensor 92, a yaw-rate sensor 93, a lateral acceleration sensor 94. Motors A and motors D are controlled by the electron control device 102 to reduce nose drive, squat, and roll of the vehicle based on signals from aspeed sensor 95, a steering angle sensor 96, a throttle opening sensor 97, a brake sensor 98. In this case, a steady angle is corrected so that the smaller it becomes, the smaller the ratio of steering torque to the steady steering torque, and the road clearance adjusting means A-D are controlled based on the steady roll angle after the correction.
Abstract:
PURPOSE:To improve control performance, in the relation of the slip control device of a driving wheel for control driving force properly so as to suppress slip of the driving wheel at the time of accelerating and decelerating of a vehi cle provided with automatic transmission. CONSTITUTION:A target slip ratio is multiplied by an estimated car body speed (step 101 to 103). When the value of a maximum wheel speed is speedier than a value multiplied a judged slip ratio by the estimated vehicle speed, slip condition is judged, and the value of the front and rear accelerating degree (Gx) of the vehicle is set to a maximum car body accelerating degree (Gmax) (step 104 to 109). The target torque of a torque converter is calculated from the maximum car body accelerating degree (Gmax) (step 110 to 113). A target engine rotational speed is calculated from the target torque of the torque converter and the target wheel speed of a driving wheel (step 114, 115), and a throttle opening degree is controlled so as to match the target engine rotational speed with a real rotating speed (step 116 to 124).

PURPOSE:To achieve a fail-safe function for rear wheel steering control using a simple configuration. CONSTITUTION:On the basis of outputs from a steering angle sensor 41, a car speed sensor 42, and a yawrate sensor 43, a No.1 microcomputer 44 controls an actuator 21a and steers the left and right rear wheels RW1, RW2. At the same time, a No.2 microcomputer 55 controls actuators 31a-31d on the basis of outputs from another steering angle sensor 51, car speed sensor 52, load sensors 53a-53d, and brake sensor 54, and sets to proper value the damping force of the shock absorber of each suspension device 30A-30D. In the event of failure occurrence in No.1 electric control circuit unit 40, the No.2 microcomputer 55 senses it, suubstitutes for the No.1 microcomputer 44, controls the first named actuator 21a through a switching device 60, and steers the left and right rear wheels RW1, RW2.
