国産車の電子制御について考えた[CX-30][RAV4][CIVIC][ECLIPSE]


Hello everyone. It’s tiger-juice-garage channel. Today’s topic is electronic control that it has become one of main-stream in car futures. Each car company in Japan has developed several kind of e-control. each of them has variety characteristics. Please take a look this chart. Let’s figure them out one by one. Toyota’s e-control is called [Dynamic Torque Vectoring AWD]. It controls ‘torque’. So what is Torque? Torque is a measure of the force that can cause an object to rotate about an axis. Please remember.
when you ride a bicycle, you push on pedals by foot. The rotational force is torque. Dynamic Torque Vectoring AWD with Rear Driveline Disconnect will direct
50 percent of torque to the rear axle and will further distribute torque to the left and right wheels to improve handling. Like, for instance, the engine gives you $10. and here a corner comes, it distributes $7 to front and $3 to rear. furthermore, the real outside wheel gets $1 and inside wheel gets $2. This system operates to increase handling and driving stability. However you might think how this works well to correct understeer. If you can give more rotation on the rear outside tire when you take a corner, you will fix understeer and be able to take an ideal driving line. Understeer is the car does not turn enough and leaves the road. You can see how it works on the multi information display. You are like a supervisor ‘Oh the guy work hard right now’ something like that. Next, we have Honda’s e-system. It’s called [agile handling assist]. Specifically, active braking, typically on the front and rear wheels on the inside of a turn, helps you to remain stable on sharp turns and bends. This braking on individual wheels helps you to avoid oversteering or understeering for enhanced accuracy. Agile Handling Assist deploys as needed so that you can maintain performance, regardless of the twists and turns that lie ahead. It is most effective in tight corners when you’re traveling at a moderate speed. Have you ever read a Japanese comic called ‘Initial D’? There is a Gutter Run technique. This is done by dropping the tire to the gutter of the corner in order to maintain speed while attacking a turn. This Honda system likes that. Plus, in a Honda all-wheel drive vehicle has another e-control future. The Real Time AWD™ system is an electronic feature that will monitor and control torque distribution to improve traction and performance. Agile handling assist is installed into civic, vessel, s660, NSX, legend, CR-V, N-BOX, Insight, Jade as a 2WD car. Vessel and CR-V AWD have the Real Time AWD system in it. Thirdly, Mazda’s.
It has G-vectoring control Plus as an e-control. GVC Plus applies a light braking force to the outer wheels, providing a stabilizing moment that helps restore the vehicle to straight line running. It also varies engine torque in response to steering inputs in order to provide integrated control of lateral and longitudinal acceleration forces and optimize the vertical load on each wheel for smooth and efficient vehicle motion. As the driver steers out of a corner by returning the steering wheel to the center position, the system will work. Here is freaky example though, the engine produces $10 normally, but since the corner comes, the engine reduce $6 from $10 regardless of driver’s will. Then, the situation is similar to that you step on the brakes. When the brakes work, the car sinks lower than usual. So you can control handling easily and fix understeer. When cornering, GVC Plus lightly applies brake force to the outer wheels as the steering wheel is returned to the centre position. This provides a recovery moment that restores the vehicle to straight-line running and achieves greater stability. This is like it; If you put the load in the front of your snowboard, you can control easily. On the other hand, you put the load in the back of your board, you no longer control it. Just go fail. For AWD cars of Mazda have i-ACTIV AWD additionally. i-ACTIV AWD is constantly monitoring road conditions in real-time and watching for tiny variations in wheel speed that a driver would never notice. Proactively controlling the distribution of torque, which can range from full front-drive through to full 4-wheel-drive. Mazda’s i-ACTIV AWD provides drivers and even passengers a combination of safety and comfort. GVC Plus is rolled out to all Mazda models except for RoadSter. i-ACTIV is also instilled to all Mazda AWD models. Mitsubishi’s S-AWC technology is brilliant too. S-AWC is an Integrated Vehicle Dynamics Control System that realizes the AWC concept at a very high level. Its advanced integrated control manage the driving forces, like Toyota and Mazda, and braking forces of the four wheels, like Honda future, to help realize vehicle behavior that is faithful to the operation by the driver under a variety of driving conditions, making it possible for “anyone to drive comfortably with peace of mind.” Eclipse Cross and Outlander apply to the function. All right, that is all for today. I think e-control doesn’t stand out rather than exterior a car has. However you might take it for granted in the future. Many car companies aim at the same purpose to fix understeer. I’d like to enjoy driving life with electronic helps I introduced today. Thank you for watching! See you soon.
