A leaning posture control device controls a leaning posture of a left-right-inclined-wheel-equipped leaning vehicle. The leaning posture control device controls a torque of at least one of a left inclined wheel or a right inclined wheel arranged in a left-right direction of the vehicle so as to suppress a change in a lean of the lean body frame in a left direction or right direction of the vehicle while the lean body frame is leaned, based on a physical quantity concerning side-slip, in the left direction of the vehicle or in the right direction of the vehicle, of the left inclined wheel, the right inclined wheel, and another inclined wheel disposed ahead of or behind the left inclined wheel and the right inclined wheel.

A lean angle detection sensor detects a lean angle of a vehicle. A storage portion stores a second relationship that represents a ratio of a braking force of a front wheel brake to a target braking force for each lean angle and/or a third relationship that represents a relationship with a ratio of the braking force of a rear wheel brake to a target braking force for each lean angle. A ratio setter determines which second relationship to refer to among the second relationships stored in the storage portion based on a detection result input to a detection result input portion and/or determines which third relationship to refer to among the third relationships stored in the storage portion based on a detection result input to a detection result input portion. The ratio setter sets a ratio of the braking force of the front wheel brake and the braking force of the rear wheel brake based on the second relationship and/or the third relationship.

Brake device and saddle riding type vehicle

A driver operates a shift pedal to perform shift change of a transmission via a shift mechanism provided in a vehicle. An operation of the shift pedal is detected by a load sensor. When a sliding gear and a fixed gear of the transmission continue to be separated from each other for a predetermined period of time or longer after a shifting operation by the driver is detected by a load sensor, the rotational speed of the engine is maintained within a target range by an ECU.

To provide an algorithm-based optimizing controller which can search for an optimal solution in line with user requirements with reduced time requirements for optimization. An interactive optimizersearches for an optimal solution of a responsivity calculatorusing a GA while repeatedly evaluating, interactively, responsivity outputted from the responsivity calculatorwhich receives control coefficients that affect control characteristics of the interactive optimizerand outputs the responsivity. An autonomous optimizersearches for an optimal solution of a fuel consumption calculatorusing the GA while repeatedly evaluating, autonomously, fuel consumption outputted from the fuel consumption calculatorsuch that the responsivity will be within a predetermined range based on the responsivity determined from the optimal solution found in the optimization of the interactive optimizerusing the fuel consumption calculatorwhich receives control coefficients that affect control characteristics of the autonomous optimizerand outputs the fuel consumption.

A technique for estimating the best children (i.e. the next generation of individual chromosomes) for use by an online genetic analyzer (GA) is described. One embodiment provides a method for evaluation of a GA in a control system for controlling a plant. Individuals are evaluated using data for evaluation. The data for evaluation is categorized into subdomains of a larger evaluating domain. Data for evaluation is sorted into an evaluation domain wherein an evaluation value of each individual is replaced by a model of coefficients relative to a standard model. The standard model is used to calculate an evaluation value. The evaluation value can include a mean value and/or a distribution. Moreover, the mean value and distribution can be valid for an area including a periphery of the subdomain. The evaluation value can be calculated as a model obtained by using a least-squares method to find coefficients relative to coefficients of the standard model.
