If you are deeply rooted in the latest BMW developments, you may remember that you have heard of the “heart of joy”, the latest step forward in the vehicle computer performance. We talked about what BMW’s heart of joy has already achieved, but now we have real insights into how – and what – exactly the mysterious black box does. We talk to Christian Thalmeier, an expert in driving experience with BMW, to get a better area.
In the heart of joy – BMW dynamic performance control
The heart of joy is the attempt by BMW to grasp the real potential electrical drive trains. Christian starts explaining the advantages – and challenges – electrification. “You need new approaches to control this force. And with this force you can influence the dynamics of driving, ”he says rightly. Electric motors can also recover brakes and energy – something that it obviously cannot – and offer an exponentially faster reaction.
With the electrification, there is also the possibility for more than one power source. The presence of two or even three or four power sources offers a much greater ability to manipulate vehicle dynamics. BMW needed a system intelligently and capable enough to bring all these advantages into the top of their cars and to consolidate their legacy as an ultimate driving machine into electrical age.
Enter the heart of joy, driven by BMW Dynamic Performance Control Software, a fully tailored vehicle dynamics control system. Thalmeier says it is a premiere in the automotive industry. The first control system developed completely internally and 100 percent in possession of the OEM. The development lasted three years, but the result is cars that, according to Thalmeier, “drive better than today”.
Heart of joy advantages; Bad news for brake makers
The conventional architecture is based on two different units – each with a drive train and dynamics. The dynamic power control eliminates the latency between two systems in favor of an integrated unit that processes the entire heavy lifting. According to the BMW, the latency is estimated to be less than a millisecond. This leads to a faster reaction everywhere in the drive – brakes (repeated or regularly) and accelerates. “From parking maneuvers to the highway,” says Thalmeier that customers will benefit from the heart of joy.
The heart of joy works ten times faster than the old systems of BMW, and it has quite a trick bag. A vehicle can bring to a full, smooth stop without brake disc intervention. According to the BMW, Heart of Joy will be able to deliver up to 60 percent more recovery than the EV generation of 2021. In fact, almost all delays can only occur through relaxation – BMW says that rain in “normal driving scenarios” 100 percent of Work can do. Bad news for brake manufacturers. According to the BMW, the system’s smarts increase by up to 15 kilometers during cross-country trips by up to 15 kilometers. The torque can be shared from one axis into another, so that the car can make compensation for over -tax and sub -control over the course of the fly.
Situational stop
When driving regularly, the heart of joy begins to relax from the rear axle when the driver lifts the gas. It is more efficient, says Thalmeier, starting from the rear axle before exerting the pressure on the front axis. However, the system will adapt in different scenarios. In a curve, for example, the performance can be brought to the front or rear axis as required to ensure a balance between over and under control.
While traditional vehicles – and many current BMW EVs even – are dependent on various drive modes and brake settings to stop, new class and Heart of Joy use the best stop tool for the situation. This leads to almost all support events that are taken over by rain, while the brake discs are only reserved for a very strong delay.
The heart of the Joy Supercomputer will be the heart of all future new class -BMWs in the heart, be it a single, dual, tri or quad engine. We expect us to learn more about how the new technology works in real life later this year if we can drive the BMW IX3 (NA5).
