A vehicle control system which can ensure high reliability, real-time processing, and expandability with a simplified ECU configuration and a low cost by backing up an error through coordination in the entire system without increasing a degree of redundancy of individual controllers beyond the least necessary level. The vehicle control system comprises a sensor controller for taking in sensor signals indicating a status variable of a vehicle and an operation amount applied from a driver, a command controller for generating a control target value based on the sensor signals taken in by the sensor controller, and an actuator controller for receiving the control target value from the command controller and operating an actuator to control the vehicle, those three controller being interconnected via a network. The actuator controller includes a control target value generating unit for generating a control target value based on the sensor signals taken in by the sensor controller and received by the actuator controller via the network when the control target value generated by the command controller is abnormal, and controls the actuator in accordance with the control target value generated by the control target value generating unit.

A side sill garnish at the outside of a side sill of a vehicle has a garnish main body as an outer surface of the side sill garnish; and a sound absorbing member provided on the inside of the garnish main body, and has a rigid member at an outer periphery of the sound absorbing member. The rigid member is attached to the garnish main body. Preferably, the sound absorbing member is made of a foam material, and the rigid member is formed by compressing the foam material. For example, the sound absorbing member, made of a foam material, has portions for fastening the sound absorbing member to the main body using clips; and these portions are formed by compressing the foam material. In another example, the sound absorbing member has rigid members on opposite sides in the outer periphery, and the rigid members are attached to the main body.

A floor structure of a vehicle body capable of enhancing rigidity against a external force from a side of the vehicle body includes a pair of right and left side sills, a pair of front and rear cross members provided between the pair of right and left side sills, and a floor panel surrounded by the pair of right and left side sills and the pair of front and rear cross members. The floor panel is provided thereover with beads in a concentric arc shape spreading from parts at which the side sills and the cross members are vertically joined to each other. Reinforcement members are provided at corners defined by the side sills and the cross members in such a manner that the reinforcement members are slantingly placed and joined to the side sills and cross members.

A vehicle floor structure including: a floor tunnel frame arranged along a center in a vehicle width direction and extending in a vehicle length direction; side sills arranged on the right and left sides of a vehicle body and extending in the length direction; lateral frame members connecting the tunnel frame with the side sills; floor panels bridged between the tunnel frame and the side sills; obliquely extending portions provided on at least one of the lateral frame members and extending so as to be inclined to the length direction in a planar view, connecting respectively with the side sills; and concentric arc-shaped beads provided in the respective panels, with centers respectively at intersections of the side sills and the obliquely extending portions, wherein at least one of the beads has one end extending orthogonal to the side sill and the other end extending orthogonal to the width direction.
